[@McFazzer][@Ozerath] Yep. Luck as a stat has been removed. We tried to make it a crit rate or accuracy of some sort in order to replace the whole drop rate thing, but it didn't really "work" too well. 

Game wise though, one can influence drop rates via certain Ancient-class weapons (assuming they land the killing blow), consumable items and such.
