I think the goal is for there to still be best stats, it's something they definitely like, but they don't want crit to be worth 10 dps per rating and mastery to be worth 6 dps for exemple.. or even less. For some classes, their best stat is thrice is good as their worst, making their worst stat pretty damn horrible.
They probably want you to use warforged gear over non-warforged even if the stats aren't optimal too.
Also, i don't see what is so bad about dropping mushrooms during hurricane? If anything is clunky, it's simply mushroom placement/detonation, as theyve always been that way, but it gives us something to do while waiting for that long channeling time, and could mesh with the watering mechanic without feeling horrible.
