the interface is not designed to work hand in hand with the player to help him find a MP game of his choice...
MP can just be a painful process in public
2 persons on my quest (europe), let me guess on which MP they are ?
95% chance they are on MP0 but then if they are on MP 8 ?
with some luck I might have to start 10 games to find people to play with ?
not discounting the 30s wait time to "find a game" each and every time ...
then maybe I find they are on MP10 but MP10 is too dangerous for me, so I change quest & repeat the whole process ?
the worst is that YOU, blizzard staff, knew this would happen, you even made some blog post about it http://us.battle.net/d3/en/blog/8414560
and I proposed some solutions : http://us.battle.net/d3/en/forum/topic/7681548457
you probably thought about some too ?
so where are they now ?
please, show us that blizzard is still as great as ever, do something yesterday !
