It's glitchy because its a mod made by a small team, and is still being updated and changed. New features bring new glitches and errors. I can live with that.
It's not really that grindy. 30->35 takes a LONG time, but you don't need to do that. It's the same difference between 25 and 30 power-wise, and at 25 most builds are strong enough to compete against level 30/31 builds. Retiring for looms over and over isn't required either, since almost every active clan has enough loomed items sitting in the armory to put something in every single slot. You gain an edge for grinding past 31 but it's not like a level 30 or 31 build can't kill a level 35 guy.
Hope you change your mind and come back. You can take a break, no need to delete everything and never come back!
