If they do want to remove it, how are the chances players will get decent enough drops/crafts to challenge high MP Inferno?

Most players only get trash drops so far, without AH, some wont be able to complete MP3 inferno with current drop quality situation.

Too easy to get legendary quality drops also will kill the game, later, most will rant this game is too easy.

MP/Uber bosses are made to make the game tougher and challenging.

Imagine there's no MP/Uber bosses. I guess D3 would have been abandoned much earlier.

after expansion Ros

some will say D3 is better
