The only problems that grind my gears in Gears:
1. Being forced to be Marcus/Drone, especially when I never left the match.
2. The cover glitch that only happens to the 3 Kantus characters http://forums.epicgames.com/threads/...ntus-LE-glitch
3. Inconsistent bot names and models: Marcus bot = Anya *? Classic Cole bot = Marcus *?
