Well, I don't want to be a jackass here, and I usually don't complain all that much about drops and whatnot, but although I agree it's important to make higher difficulties more rewarding, I disagree with how you proceeded about it.
You did not actually make T1+ more rewarding, you simply took something away from Master and below.
Essentially, you just made set pieces even harder to farm because at least at lower difficulties, monsters die very quickly, insuring more drops per time played.
I think the general consensus was: to farm XP, farm the highest possible difficulty where one does not die or spend hours killing elite packs, and to farm for gear, farm the lowest difficulty in order to get more drops per time played. Granted, a 100+ paragon farming Normal difficulty isn't how the game was intended to be played, but again, you just made our lives even harder.
I fail to see the improvement here. I, for one, was not farming at Normal difficulty because I tried before, and I fell asleep, literally: it was too boring/easy.
The solution ? Bump the set drops a bit, which I'm sure is a very unpopular suggestion amongst the decision makers, however...
