I remember the system from Dungeons and Dragons Online, where each quest have difficulty level that can be chosen before the quest start. Basicly, the lowest level is solo, and rewards in this level are also the lowest, more chalenging options requrie a partner or two...
I would like to see the same system in TOR, i'm not a big fan of groouping togeather... One thing is to find good teammates, second is to believe that they all have time to play the Operations...
Also, one of the biggest thing that i simpy love in TOR are voices in the dialogue. I dont want to skip it, but with the team, especialy if some of them already did this operation, it's something i must do
