O i understand the logic they are using...i just think its stupid and forcing us to not do good dps cause everyone needs to get a trophy and i cant do good dps anymore cause it isnt allowed. Running an effective rotation using everything the game gives you, to include pots, skills, and ults was too much for people to handle so we all need to do things so slow its boring.The whole point is that you get the buff from one source and it won't stack with itself.
I don't think they're going to change that...
The potion is still useful if you don't have that buff through some other ability.
