I would like you to remove OHKO moves from bosses, especially on hard difficulty because:
1) they disregard acc/ evasion changes, thus ignore any team composition or strategy involving
2) they are basically a 30% chance you loose the battle for no reason and without any counterplay (exept focus sash on all your pokemon, which is impractical)
3) bosses have infinite pp, making OHKO moves especially unfair
I don´t know about you guys but I would rather fight lvl 200 mega mewtwo than OHKO moves.
