Hi
I think most people dont use the Click Buff much, because they are to lazy to click so often.
So here a little "upgrade" sugestion why not give it (as same as the crit Buff) a second buff such as Clicks per second
it could be like the click Damage 2,5/5/10/20 Clicks per second while the Buff is up

I guess many People would use it much more often and i think it would be not too strong as Bushwacker gives 10 Clicks per second and rare and epic buffs are quite rare (in comparison to the common and uncommon buff)

Greetings
Dirk
