Keep this on topic please. Insults are not arguments.
We are talking about minor heal with mouse control pressed. Bug, tho I see more negative results from it than good. Slow clickers sure benefit from this, yet the benefit is bound to being able to heal 1140HP max in less than 2.5 secs, but after that, cooldown of mana pots kicks in. Also, this can be done even faster with keyboard.
BTW, having several minor heals in the same bar and pressing them all at the same time aint a bug too? I mean, no other skill works that way. Like adding pots in 123 and pressing them all together to pot 3x faster? Cause minor heal works that way and in my opinion thats a bug too. Dont see why that's more legit than right clicking the mouse with control.
