kMS videos after revamp.

That's a poison-weak boss, and don't assume mages are still weaker than other classes.

I'm really confused by what skills I should be getting once BB hits, since the whole DoT mechanic is still up in the air. I'm assuming Paralyze spam with maybe Poison Mist and Fire Demon would cause max damage, but I keep hearing about Composition and Breath. I REALLY do not want to get those skills.

Why not?

Just sacrifice a bit of MP eater and Resistance like current mages do now, both skills are very lolworthy, Poison Brace and Comp are pretty essential for DoT DPS. Also iirc you cant use Fire DoT with Poison DoT.
