My static group has downed T5 multiple times. The other tank in my group plays on the PS3. In terms of hindrances in coil, the only problem that has really affected us is his lag sometimes (probably not the PS3) and he has some trouble avoiding divebombs. The real problem was the rendering of enemies in T4, but we just allow him to OT during that turn. Other than that, we've found a way around it and he does fine.
