Carbon's pretty soft overall but the traffic and schedule isn't that great – it's kind of along the same line as AP/UB except I think the player count is even less …

Yes peak traffic is around 6-7k and the tourney sched is light. Soft is a good general description of the play on Carbon which is the Merge network and has many skins. The fields are smaller and I would suggest sticking to the guaranteed events which at times have an overlay.
