The problems I have with cover in UC3 are.
The transition going into & over into cover are too slow & clunky.
Button Mapping adds to the headache because the two most effective evasive mechanics are assigned to the same button & they tend to clash alot.
A cover based shooter like Uncharted could be so much better if the game & mechanics were more fluid like Gears, shouldn't take me 3 seconds to jump over cover & before I can get in, i'm dead because i'm left defense-less & open to getting shot from people 20ft away.
And if cover became much more useful, I wouldn't mind ppl utilizing it more often and becoming dependent on it. I usually start TDM games off a bit aggressive. I sprint over to the enemies spawn area and trace their steps back to flank them. So if they wanna camp in cover, they're just asking to be flanked.
Did any of you play Red Dead Redemtion? I think the cover system was pretty good. Quick and effective. I also like the fact that you can slide quickly from a certain distance. Though I'm not sure if it would suit Uncharted.... maybe
