I just got to T11 and it does look like my BLM will not be of much use. I have only 30 min experience in the fight so I can't help you out too much. The only thing I guess I've learnt is to all stack up behind the boss in the middle of him so you minimalize the distance you have to run and use procs when available. Have yet to see the add phase but have seen a SMN video. You don't necessarily have to move with the target or do you? I mean, yes, in time you'll have to move around because it will be out of range. But it seems to me like you can nuke it fairly well while standing still ... I'll have to find out for myself. If BLM doesn't work out, I'll probably go SMN on that fight. Don't think I'll be able to get to 406-10 DPS like on T10 and it's also a race so ... I guess we'll have to see
