All good, i am genuinely interested to delve further into this topic to see if it goes beyond the surface. I didn't realise your point was 3rd party

ok...sorry Adam for the late reply but I went to bed last night before you replied to me.
Ok, so....why do people critique C2's MP? well....aside for the obvious that you cannot please everyone the problemis that some people feel betrayed by the multiplatform switch. They will never see anything as being good on its own merit because "crysis 2 is not an exclusive anymore there fore it is consolized in all its aspects and cryteksold out" and so on ad infinitum. Paying attention to this Kind of critique is a waste of time because it is as far away from being objective or constructive as one can get.
others may see the "model" you chose for the MP as a carbon copy of COD's MP (you know...levelling up....lacking large vehicle gameplay, designed for quick matches etc...). Now, these people may or may not see the Nanosuit as something more than a gimmik because they literally stop paying attention once they realize this is not "powerstruggle" or a long drawn out attrition MP variant involving vehicle battles and such. Balance also seems to escape them as does the "rock paper scissor" like system you put in place for people to counter the powers of each other nanosuit.
As for me, having played SOME Gears of war 1 MP (and thus knowing what straightforward shooter mechanics look and feel like) I can tell that yes the nanosuit is a central gameplay aspect of the gameplay and so are the interactions between upgrades and modules.
My only suggestions would be, since I am not much of a competitve mp fan, to add a "firefight" or "horde" mode to the MP.
That...and for the competitive MP I'd say, since people complain about it bwing to COD-ish, to do something like it was done with the latest Turok. Yes that game had serious issues BUT they did add something nice to MP and that is a neutral 3d faction. Yes you have the marines and the CELL agents duking it out but the introductions of the cephs as a neutral 3d faction hostile to both teams and responsive to stimuli (attention drawing and whatnot) could provide the necessary omph to dislodge some people from their preconcepts
