Why wouldnt u ragequit sometimes, poor hit detection/networking/whatever (something is very wrong in that department), sound that abruptly says: "screw u, I'm going home", some maps where u have crosshairs which are doubled, stats are still very random, lockdown timer, protective area instant kills, damn upgrades which u can't remove anymore (lovely to have an extra meter of rifle sticking out a room), ...
And to stick with your point, you can now go on a TK rampage for half a match, leave and nobody loses anything so I don't see why there would be more quits halfway through matches compared to how it is now.
There is no running from stats if they're saved in real time, like nearly every other game
When all those things are finally taken care off, I might see this title gaining some rep back but at the moment, I don't see it regaining strengt any time soon.
Good thing that first click has FINALLY been fixed, it's only been like this since the beta?
So ye, thanks for that
