I agree the low stat rolls shouldnt happen. This makes the insane grind pretty useless. Then again, i think the idea of the exotic focussing is more aimed at an extra chance to get the armor piece you want and because this is endgame gear we are talking about, it shouldnt be easy to acquire. Also, you should be grinding GMs if you want to earn godrolls. It basically always guarantees high stat rolls. Maybe not the exact piece you are looking for, but a godroll nonetheless. You'll have your vault filled with all godrolls pretty quick. Tldr: Grind is ok Low stats is not ok Farm GMs
