OP is full of shit. It takes them years to fix the damn dedicated server security holes and they're still working on it... do you know how much work and testing it would take for them to add two new vehicles (amphibious at that) and have the sentry gun stop detecting and shooting through titan walls?
Nevermind the shit about "screenshot lag spike" which is impossible to remove, and "titan explosion lag spike" which IDK wtf he's talking about.
I'd be EXTREMELY surprised if DICE actually made any changes to 2142 except very little things (damage, firing, recoil, etc. adjustments, pod rotation speed, spawn locations etc.)...
