Hello! I usually don't give my opinion on the state of the metagame, but I feel like it can help the discussion not only towards Roaring Moon, but about a deeper problem we are facing.
First about Moon, I will personally be voting ban. Taunt is the best set, being able to shut down common counterplays like status spreaders is huge. To top it off, Acrobatics + Knock Off is sufficient to break down almost every defensive core. Coverage options like brick break can even help against Veil and Kingambit. Even if you will not see Moon cleaning every single game, the immediat progress it provides to any offensive team is not negligeable, and opens paths for way too much threats.
However, I also wanted to raise an issue that I personally feel is underspoken. Energy booster gives way too much snowball potential and enables HO to run 2/3 booster abusers. Threats like Valiant, Moth and even Tusk to some extent, benefit a lot from this item, making them faster than the whole metagame. You usually try to force them out and your gameplan revolves around 'how can I make them waste their booster?', or maybe revenge killing it. It even snowballs to an extent where people are using Destiny Bond Valiant as fodder, because they’re aware that once Valiant gets out of the field, it ends up being a deadslot. In the case of Roaring Moon and Walking Wake, this item gives them insane wallbreaking abilities, and both having a move to boost their speed makes them able to heavily snowball on small positionning mistakes. Iron Moth even has the privilege to run both options (webs makes spa boost moth even more threatening).
Monotype banned that item because of its potential, we banned gems in BW, and Light Clay was discussed in home (Magearna was still around, but that item still caught some attention). Without energy booster around, those abusers will be more maneageable, and building around them will ask for more game insights than just stacking strong win conditons that can snowball heavily.
Also wanted to quickly touch on hazard stacks. Spikes are adding so much pressure into the builder, we even run teams with 4 to 5 boots users. Vert already pointed out that problem in the Home metagame, and with the addition of the best spiker we’ve ever had in Gliscor, the issue has only grown. Removing hazards is harder than ever, especially with ghosts being so strong and having defog users struggling to pressure Gholdengo. I’m not the most qualified person to speak about this, but keeping an eye on spikes and Gholdengo should be another priority.
Furthermore, some thoughts about tiering in general. Helding surveys is great, asking for the community’s opinion on the metagame points out what evebody finds broken, but it makes decision making as a whole a lot slower. I don’t think we should get rid of surveys, but being able to take initiatives without relying only on survey opinions is important. Blood Moon was obviously broken, but we decided to go throught a suspect instead of a quick ban because surveys didn't point it out as a serious issue.
That's it! Hope everybody is able to reflect on their opinions before voting! Thanks for reading!
