You waste your time on mp8/9 and then talk of efficiency?
Monk tempest rush and Demonhunter are the fastest paragon levelers, not Barb.
Barb is just OP and cheap to gear, thats all.
Fastest paragon levelers you say?! Isn't it the first character to reach paragon level 100 was ding! ding! ding! ding! our survey says BARB - Alkaizer.
Except things have changed. There wasn't MP0 back then and gears were worse. Nowadays every class melts MP0 A3 and barbs ain't the fastest.
