If all people are going to do is follow the same strategy every gen than that's just going to make things stale. It makes more sense for them to try and break out of this stale state and try to get people to do some other stratgey and overall just make battles less about finish it quick and more about nail bitting thrills.
It doesn't matter in the end, unless they get strict with things it's just going to be the same deal as always. There's at least two sides to Pokemon that lets everything get used. Simply more potential that can be got out of that, just goes overlook.
Yeah...that's true...I just kind of wished that there would be more walls this gen considering that the majority are built to be lackluster offensive tanks (honestly the most effective item for the bulk of this gen is an AV, CB, or CSp)...only toxapex (and to a lesser extent cekesteela) really excels with its stat spreads and movepools while the others are easily picked off by standard offensive builds of old 'mons like mega salamence. For a good solid three weeks, I used nothing besides new 'mons and unless I brought pheremosa or scarfed xurkitree, mega mence destroyed my team every time no matter what team. TR, hyper offensive, stall, terrain abuse, etc. Especially with the t-wave NERF, it makes it even harder for slow offensive 'mons to shine. I mean I'm not an amazing battler, but I did much better last gen with 'mons like klefki, goodra, meowstic and mega lopunny
One Pokémon that I had more hope for was primarina actually. With its typing and movepool, it would have made a great stalling rest-talker...if it had stats like milotic's like I had hoped (and serene grace as HA)...in the end, it's again best used as an AV/ CSp tank albeit one of the better ones.
Speaking of T-wave Nerf though, I do believe that a lot of these new 'mons would see more play if the old T-wave was still in place though.
