I 100% agree around like 60% of decent attackers still spam insane moves the only difference is that with choice sets there's no life orb but choiced + plate+ move boosting item is still 1.98
I believe that while choice items broke the game the restriction CERTAINLY helps but i think smth like specs/plate/life orb/ type booting item spam is still viable which in total is never healthy the day when a mon that has 1 move it the day when we know smth is wrong as always I'm happy for...
I agree with Inky completly because so many mons with decent offensive presence now become uncheckable nukes and there are so many that it's not a matter of bans unless its to choice band and specs.
252+ SpA Choice Specs Tera Dragon Raging Bolt Helping Hand Battery boosted Power Spot boosted...
I think that a metagame where having something like Choice spec's , life orb, wise glasses, freeze plate, choice scarf Ice beam from kyurem is not sounding very healthy.(I might be wrong and I'll be happy to see some disagreement.)
Funny enough I use that exact move set (in that order) but I'd invest in attack a little more as a few mons might live quite a few unboosted facades and knock offs. But the spread you are using right now is also solid I like the bulk.
