I'm going to have to move regardless of whether I'm standing on a platform or elsewhere in the arena(also being a machinist I'm given plenty of opportunities to move without messing up my rotation) and if both platforms on one side are gonna get puddles on them then you're given more than enough time to move around to the other set of platforms, even easier for melee players than ranged. But I'm guessing this is something we're not really gonna be able to see eye to eye on.
