IMO I think part of why theres less people playing SV OU compared to last gens is that :
- SV was a very undercooked game that came under fire a lot for being unfinished (I am not getting into my thoughts on SV as a game as that could legit be its own post somewhere else)
- People are playing other formats, be it mainstays like VGC or low tiers, or new ones popping up
- Many older fans have reached a point where they are ok with skipping a gen of comp, and are fine going back to their old reliable favorite tier
- People who just dont like the tier
- People who would've played it but were told not to because their buddies say its just a powercrept HO filled wasteland
As someone who just took a 4 month break, I think power creep is a legitimate complaint. It limits a lot of playstyles. I doubt a significant amount of people are avoiding the meta because their friends are telling them to.
The meta is more offensive and favors (at a high level not like 1600s) players who are better at/enjoy those styles. It becomes kind of cicular as more of those players get reqs (including some quite vocal YouTube grifters) and then less pokemon are banned (this could go the other direction too just how it broke this gen).
l actually think a lot of players conflate issues with Tera and power creep. We’ve had some more balanced metas this gen without Tera being a problem. It’s really now a select few powerful pokemon that either are new to this gen or were let into the tier when they arguably should not have been.
