Not sure how this is competitive. Most of the strategies being used against Cinderace aren't even what's "meta" right now. I grabbed a Slowbro I had in my box from my dex completion, gave it the aforementioned moves, leveled it up a bit, and won easily without worrying about EVs/IVs. Did the same with a Daschbun to help a friend. I don't think having to use some easily obtainable items to invest into a Pokémon for 1 battle is hurting anyone.
This is very simple strategizing compared to actual competitive. I can understand why it's seen as a bit too much and I agree it can be overwhelming though. Not a fan of the shield gimmick they somewhat kept from SwSh and the online often lags to where the Tera Pokémon gets hits in without me being able to do anything.
What Wulava said. It's far too limiting in terms of need specific combinations of Pokemon, movesets, stats, abilities, and items. If you've gotten to that point, you've gone too far in the competitive direction for the average player to keep up with. That's not just "simple" strategizing by casual standards. Again, I don't want to be locked into specific builds for specific Pokemon just to win something in-game. Let me use my favorites instead of having to worry about all of that.
And the items needed to maximize your movesets, stats, and abilities aren't really "easily obtainable" either. At least not to the point where you can casually dump them onto a Pokemon you weren't planning on using. I'm still trying to grind up my main team to Lv. 100 (and a few other Pokemon I think might be useful for Raids my main team can't cover) so I can't spare the EXP Candies for a new Pokemon right now. I have a few Mints, but not quite enough. And I only have 1 Ability Patch and a handful of Capsules and Bottle Caps. It's not like you can just get these resources with the snap of a finger, it'll take a few days worth of grinding to get them, and it's still fairly early enough since release that most players probably won't have stockpiled enough of them for something like this. And the mid-January re-run might not even be soon enough.
