So I tend to rag on Summoner a lot. And the job has plenty of problems. But goddamn is Bakka a whole lot easier when you can toss a disposable Ice-immune pet at him and watch from a safe distance.
Goetia Chain for a while now, but always went as NIN/DNC. Violent Flourish is a pretty reliable Stun, but he can get pretty spamming with -gas and all his TP moves being AoE and shadow stripping. You, of course can't use it while you're Amnesia'd.
