Oh I never tried much crafting besides jewelry
Can they roll the max amount of sockets ?
An endgame bowzon can possibly have 4 rare items in BIS gear list. AND this is without the idea you told us. So many things related to rares should be changed before this happens. I'd say we might see this in 7.0. Technical part is not even considered because these are all hard coded things in the game.
What I would like to see is a huge nerf in rare item drop chances BUT buff the variables on the rolls. Variables are absurdly wide and choices are much more than vanilla Diablo, so having a decent rare item is a huge pain in the ass and most people don't even bother. This change would get rares back into the mod. Most of you probably know that in last ladder, before I quit playing, I wanted a +4 bow %30 ias + %20 attributes gloves for months. I offered 30 runes, Frostmourne etc. to whoever finds one yet no one had it. Because no one was looking for it.
Well short of the story is you had one, I had a godly belt and that's about it. Good rares are TOO rare to find.
