It's unfortunate this thread has just devolved to arguing when these comps are an actual problem, especially on Shatter (I don't care about what you think of Shatter). I saw a team win by reaching the score limit of 2000 with 1450 being from player kills. They almost completely ignored the objective entirely and just nuked whole teams. "Just Guard" doesn't work when there's 6 ASTs on the same team all running together behind the same DRK that they're pocket healing.

Specific jobs aren't the problem, but allowing that type of party comp sucks out any remaining fun in Frontlines. I can't queue for casual Crystalline Conflict with one friend but people can do this? Sure, yeah, that makes sense.
