What I see there is a complete disregard on the BLM for tryin' to land another sleepga II after knowing they don't have the time to recast. Could a sleepga 1 save that run? Sure could've, but hard to tell when the BLM didn't try. From my experience I would always throw a sleepga 1 when the mobs would wake then throw a sleepga II on top of that after waiting a bit to make sleepga worth the trouble.
It is a good bit of info at someone's expense to prove how vital a subjob can be though.
