In at least two of the arena maps, people are able to sit in corners with there backs in the corner so my partner cannot use his mutilate ability or any such attack from that is required to be behind a target. Is this supposed to be apart of arena or is this an environmental exploit. Please reply or fix!
Keeping your back against a wall and protecting your kidneys and other weak spots is a pretty good technique. Nothing wrong with some situational defense.
The trick then is drawing them away from the wall then, isn't it? Go Gladiator, kill, for the glory of the horde.
