I do not agree that weather should be banned because of the decline in usage of specific Pokemon, in the same way that I do not agree that weather should be kept because of it brings variety (which it does not anyway because only a small number of Pokemon would fall back to UU without weather present - Vensaur, Toxicroak, Excadrill.)
I do however; believe that weather should be banned for the following reasons.
It is my belief that the enjoyable ‘old style of battling’ has been sadly lost and replaced with the tiresome never-ending weather war. Opponents desperately compete with each other for weather control because without it they will almost surely lose. Let’s face it, the Metagame is now solely based on who can keep their weather starter alive the longest so they can sweep the other players team. (Or what team can I make to counter the most weather abusers.) Honestly, I do not feel that this version of battling is even enjoyable or in my opinion more skilful than the previous way we battled. Before we had to outsmart the other player through our use of skill and tactics, now through the loss of one or two Pokemon (whether it be a weather starter or the main counter for weather sweeper ‘X’) we can easily lose the game. At this point you look back and think, is there any way I could have possibly won from point ‘Y’ if I hadn’t done this, or hadn’t done that, but more so we find ourselves thinking that it would have be literally impossible to win from this point. This is not because the opponent superiorly outsmarted us; it is simply due to the fact that based on our team we couldn’t have possibly won. The threat of weather has just become too strong in my opinion. We shouldn’t be doomed to lose a battle (so early in the game) just because of the ‘death’ of one or two members of our team. Yes, they are a few scenarios in non-weather teams where this occurs, but with weather it occurs too often. Which I feel proves that something is wrong with the Metagame.
Now, I liked the way this started out, because you got right to the heart of the matter. But in the middle it started to go downhill.
You said that the loss of one or two Pokemon often means you lose the game. It has always been this way. Last Gen, if your opponent had an SD Luke/Scizor, and you lost one or two Pokemon (your counters/checks), then you could very well lose. Or if you're playing full Stall, and you lose a couple 'mons, your team is handicapped and you could very well lose. If the opponent beats a couple of your 'mons and then sweeps you, it means that they out-played you. It has nothing to do with weather. In any battle that you lose, there will always be a "Point Y" that you can look back to and wonder if you could have won. Any battle. My point is that, the death of one or two team members can make you "doomed to lose" against any given sweeper, not just weather threats.
Can people please stop saying that the metagame is just weather wars? Weather wars are a huge part of it, yes, but the new statistics show that it continues to take up less than half of all teams. All of offense in Pokemon is about getting favorable conditions to make a sweep, and weather is just another way of doing that.

Now in the case of Non-weather versus weather:
In the last generation of Pokemon, Sweepers could be handled in two ways, either through the use of counters or revenge killers. However, choice scarf sweepers are no longer able to outrun the main OU sweepers in this generation, as in comparison to their 1.5 speed boost, weather sweepers get a greatly superior times 2 speed boost. (Side Note: choice scarf sweepers are balanced by the fact that they can only stick to one move, where as weather sweepers can freely switch between all moves). This means that we can only rely on the use of counters to stop heavy sweepers in their tracks.
Choice Scarf is not the only way to revenge-kill. There are also the kind of check which can take a single hit, then KO back. There are also the kind of check which uses priority to bring down a threat.
Not to mention that in OU, there is 1 Chlorophyll Pokemon (Venusaur) and 1 Sand Rush Pokemon (Excadrill). So it's unreal to imply that most weather sweepers are getting their speed doubled.

On this note, non-weather teams have to use counters for each of the weather abusers. This therefore only leaves a small space of one or two more Pokemon. Yes I know these ‘weather checkers have other purposes’ but considering that weather checks for each separate weather usually fails against another weather, means that certain slots on the team are useless majority of the time.
Okay, it's not true that checks to weather threats are "useless majority of the time". Lati@s, Balloon Heatran, Dragonite, they all screw over common Sun sweepers, yet none of them are "useless" against non-Sun teams. Balloon Heatran, Gliscor, Starmie, they all screw over common Sand sweepers, yet none of them are "useless" against a non-Sand team.
Dealing with weather threats can be done without devoting an entire team just to do so.

Back to my point that weather allows Pokemon ‘X’ to live ‘Y’ and Pokemon ‘Y’ to kill ‘Z’.
(Looking at OU)
Yes, stealth rocks also shares the same characteristics as this, however the damage of stealth rocks is greatly limited in comparison. Stealth Rocks only majorly effects 4 types – Fire, Ice, Bug and Flying (three of which’s pure typing isn’t used in the OU Metagame due to this heavy SR damage.) For the remaining types the damage of stealth rocks is limited to a small amount which only occurs on switching. Weather on the other hand, majorly affects the damage done to the majority of Pokemon. It has become too powerful in the sense that it completely changes the Metagame to favour specific Pokemon and put others at a major disadvantage. Such favourability for such a large number of Pokemon should not be brought on just by sending a Pokemon out without even using a move.
You say that Stealth Rock only affects certain Pokemon very much. The same applies to weather. Any Pokemon which is not weak to Fire gets no defensive benefit from Rain. Any Pokemon which doesn't use Fire moves isn't hampered by Rain. I could say that weather only affects certain things to a significant degree, just like Stealth Rock only affects certain things that much.

The importance of weather has far surpassed what used to be acceptable, and is thus creating an unbalanced game where non-weather things aren't important and get overwhelmed unless they counter specific weather threats.
This isn't true. Non-weather teams can be very successful (just ask ginganinja), without using 6 weather-counters.
Our limits of acceptable must grow as time goes on, and this is just one of those times.
