The guy getting his ass kicked at least gets a chance of wearing down the other guy. It adds a very interesting dynamic. It shoots at the same speed it pulls you in, and it shouldn't be usable as a weapon. Oh, and other problem with the grapple in CTF is that it doesn't break when the grapple line crosses through a solid boundary. Q2 actually had weaker armor than Q1.
Ease of use is far more important now than it was, say, three years ago.
Confusing as hell. Or they'd have full armor, and run over armor and it would stay there. Completely unintuitive stuff. If you can't install a game and run it, then that game is probably going to be returned unfortunately. People want to hop in and play right away, not spend three hours figuring out how to stop staring at the ceiling and walking into lava.
