I currently play The Secret World with my Co* Online group because it's the only thing we can all agree on so far that doesn't suck 'too bad' (though it has it's good moments and upsides too- even though it's still not 'home') we have had our moments, but I can see a line on the horizon as we enter Transylvania and finish the regular content there. I don't think they're going to be able to keep up with our team demands, re-playabilty aside (and since the story content seems to be SOLO for an MMO) at the rate we consume it, and we don't PvP. Not to mention the fact that when the whole 'usual gang' is there it exceeds almost any other MMO's current team limit restrictions.
That's one of my few gripes with TSW (also my 'main' these days), too: the five-man team is too small to accommodate "the crew." Or it was until a few of them put the game on hiatus while waiting for more content...but that's another matter. We regularly had to leave people out for dungeon runs or a Lair visit, and that sucks. Unfortunately, a whole bunch of content is balanced for a 5-man team (and the more challenging content for a rather
specific sort of team: 1 tank, 1 healer, 3 DPS. It's sadly ironic that in a game with the most flexible, wide-open character development system I've ever seen in an MMO, things still gravitate towards the Holy Trinity. I don't think that was really the devs' intent, either; the trinity happens because it
works, and only CoH managed to make it completely unnecessary. That was another amazing accomplishment that's largely unrecognized in the MMO community.
Don't get me wrong: TSW is the best MMO I've ever played on many, many fronts...but the several areas in which it's deficient to CoH really stand out sometimes. No game before or since CoH handled teaming better, from useful social/teaming tools, to the brilliant auto-exemplar system, etc. No MMORPG has had better "kinetic immersion" (that is, the sense of your character moving in a world with real physical forces acting on them...remember the first time you used Super Jump? Yeah...that's what I mean). And so forth...
