I'm a diurnal sect AST. Just cleared A2 and 1 shorted both of them through DF.

Honestly, Balance, Arrow, and Bole are the only 3 cards I pay attention to. Spear and Ewer I would give to myself or Ewer to a BLM if I am feeling frisky and ALL SPIRES MUST BURN!! *ahem*

Seriously though, if you don't need a bole, burn it to get the enhance, spread a Spear or ewer in case you need to lower your recast of LA or SC or reduce mana cost of an Ascend and keep your regens up on the tank and you should be good.
