Post ascension Bishop build

Forget about dps, for training the exp-per-sec is important. The hs of the bishop basically means +50% exp-per-sec. The hsless bishop would have to do dps of the whole party *50% to provide the same exp-per-sec increase. So basically he has to be as strong as 2.5 attackers assuming the hsbishop does nothing. Assuming average %stat is 50% in the party, the bishop would need the strength of 150%*2.5 = 375%, so he would need 275% int, which is impossible. Hs bishop > hsless bishop. QED

Anyways ontopic, I'm going to do this build:

1 Gen, 1 res, 1 bb
Max AR
lv. 7 or so bahamut
Max Adv. Bless
max ressurect
Max Buff Mastery
lv. 20 MW
max Arcane Aim or infinity (I can't decide which one is better)
max infinity or Arcane Aim
Max Bahamut (102 SP out of 108 spent at this point)
max genesis
max bb

I like both supporting and attacking actively, so I'm doing a mix of both type skills.
