Part of the problem is 3D gaming does not yet contain tight enough gameplay from what I've played. ie. it's too overcomplicated versus how simple things were in them 2D days (why VS fighting games are still stuck in the 2D plane even if 3D). Things need to be simplified more, yet still be deep enough for truly replayable PVP gaming.
BioWare is also not very good at balancing games yet either to handle the task of PVP.
^ True BSN babies already whine about multiplayer and its guns and stuff (acolyte included) Cough cough
that making a PVP mode will be highly impossible as it won't ever satisfy the hunger of BSN babies
as there will always be a character or gun that will be superior or crazy game mechanics that will get nerfed or readjusted
Baby milk is the lifeline of this forum. Take that out, and it's not BSN anymore. (And I'd be out of a job. Can't have that)
Complaining about what's OP and not is something that comes with playing this game way too much. As with any game anyone ever overplays. You start over analyzing everything.
