People forgetting to turn it off is what gets the hunter community a lot of hate (and lets be honest unless you have an addon set up to flash in your face when its on, its often easy to overlook).
I almost got kicked from an LFR yesterday because one of the other FIVE hunters had it on and wasnt reading raid chat, they were just going to kick all 5 of us so it didnt happen again.
I like the Idea that its a short term 'buff'. You toggle it on, everyone in your raid gets Aspect till you turn it off or until theyre struck. They get dazed once, lose their buff and its not reapplied until the hunter retoggles aspect, if the hunter is struck and dazed everyone loses their aspect buff.
Theres barely any fights you can use Cheetah in anyway without it being insta cancelled (Constant ticking damage and so forth) so I dont think it would break the PVE side of things and for PVP the whole getting dazed thing is a death sentence so its more a QoL change to prevent hard core rage receiving to new/zoned out hunters.
