Some facts to keep this discussion in perspective.
U can't minor heal more than 19 times in 2.5 secs, which is the amount of mana a 1920 soul pot has per the cooldown of it. That is 1140HP every 2.5 secs. Now, I used a stopwatch to see how many clicks I can do in 2.5 secs and average i did 18 to 20 clicks. The bug relies on the fact that u get more minor heals per click, making u heal at light speed, still u can't go more than 1140HP per soul pot (2.5 secs cooldown).
So, if it gets fixed, ppl who click fast enough will still heal pretty much at the same speed. Sure, u won't be able to heal 1140HP in 1 sec, like it is right now, but to be honest i find that much worse cause u run totally out of mana leaving u open to not even use skills during the rest of the pot cooldown.
Looking forward to see this fix so I dont hear more of this "bug abuse" thing and also being able to minorheal properly without running out of mana too fast.
