which character for running missions

as of right now ive been running missions with my imba but i was wandering for the easier missions which would be better.

ive seen sins and monks both using assassin's promise with you move like a dwarf finish him and ebon sin but i was wandering which ones better.

also if you could help with the skill bar on the last 4 skills that would be great also =].

NOTE. when i say running missions this is running other people for missions not just myself.

I had War,Ele's and Neccy's run missions for me. And about bids sorry i only know they used the AP,discord neccy builds.

Usually ppl run with neke and discordway, thanks to MoP Nuking (http://pvx.wikia.com/wiki/Build:N/A_Mark_of_Pain_Nuker) and great emanagement.

when i run discord with my sin i use the ap build and i use monk smiting sig for the high damage and you dont have to worry about recharge th to ap
hope this helps
