Found it from Zicarax who i tend to just call him that red guy
Tbh, i think they should be removed, i can easily farm about 1 potion per 1,5 hours, if someone would want to make their character more powerful after they best T1, the best way is to get these potions from DK, which you can farm really easy with T1 gear (Bosses die in seconds)
I already have about 70 maybe 80 more stats than my other charaters on my Warlock since i farmed DK for a moderate amount of time with him, if i had continued i think i would have about 500 more stats, maybe more (depending on how much i would play, but at least 500).
Permanent statpoints is also better than gear, they are permanent and wont go away. And reducing the drop-rate wouldnt solve it really, i mean, would still be fun to see one of those potions once in a while, but id say get rid of them all together so we wont have characters that are blatantly overpowered for any future content due to farming DK over and over again.
