SoC will burst after one tick with more than 3 locks, and its instant AOE.

Living Bomb is a GCD though, and can be put on as many targets as you like, which gives you the option to destroy an entire raid with a few GCDs if they don't move from eachother. if Living Bomb explodes when the target dies, that would make it really powerful, since you could put the LB on him and then scorch him to death.

I have warlocks, and play them because I like them, and I find mages repulsive.. I don't know why.
