ZeRo4 would've decimated you on both maps, if he could aim worth a damn, but, yeah, should've, could've, would've. I think he will probably do a lot better on LAN, and there's also the [somewhat remote] possibility that he's holding back more than a little bit.
In any case, I totally understand what he's saying on ztn when you out aim him with lightning at grenade launcher. I get the same problem. He had superior position, had the jump on you with lightning, and had better health/armor, if I recall, but was just no match for that ridiculously lame CPMA lightning gun, and it really makes no sense to me either.
that aside, he's getting back in shape imo - just lacking some (shaft)damage. ;)
