I know of some who have. Not sure how many did it with the purpose of regrowing, though. Most were quitting.
Myself and my alt were both t4 reset and the alt reset as LC three more times before trying to grow again.
Many t5 lcbc have reset. And maybe 1 or two t6 that I knew have reset. Some of the t5's (back when t5 was lcbc) were also VIP.
Now what I never understood,I know it's said u gain 50 tut slots when u reset,how do that work.Do a person do it before they BC to gain additional slot,or what ???
