My finals thoughts on this "debate" is I wish people would stop trying to equate this to them pushing competitive on casuals. Hate the difficulty and limitations but this isn't anything that groundbreaking in terms of strategy and most of the talk about EVs and IVs isn't necessary at all.
With that being said, I am liking that there's some level of strategy here in terms of countering them even if I agree somewhat about not fully liking the execution. Definitely better than SwSh's.
The 2 I've fought with were using Bulk Up so they were tanks to take hits and deal damage.
I think it's more of a having to use certain Pokemon thing, more than anything else.
The strategy reminds me more of regular rpg's. Having a healer, defender and so on.
