Dancer is actually really really good at Bastion if you ask me, you just cant really WS lol. SAVE THAT TP! Unless a mob is about to die because AOE is brutal. And dont try and solo anything bigger than you lol The highest i can go without getting creamed is the giant robot dolls, butlers or custodians or whatever. But the big chariots, screw that lol
Sure you can ws. What you can't really do is sub anything besides NIN and keep fan dance up.
I switched to always using Aeolian Edge. Damage as many mobs as you can and I easily maximize exp. You can average 5-12k per battle.
You can solo them to except maybe the chariot but then again I can never really get hate because it's on npcs and I just avoid it.
