So now that Perfect Defense is nerfed a bit (which was for the most part the main use of astral flow) what about adjustments to astral flow to make it more useful?
There were two potential adjustments I was thinking about for use with Carbuncle/Fenrir/Shiva/Titan/Ramuh/Ifrit/Garuda/Leviathan:
1) Make it so that when Astral flow is activated and MP is consumed, the Astral Flow pact gets an additional Magic Attack Bonus based on MP consumed. This could be, perhaps, 1 MAB per 10 MP spent. If Astral flow is used at 1500 MP, the Avatar would get an additional 150 MAB for the MP spent. Considering the amount of mileage other mages get out of 1500 MP, this doesn't seem unbalanced to me. In fact, it's still probably lower (considering that 150 MAB, stacked with pet MAB and gear likely will only double damage) than what a BLU or BLM will get but at least it is perhaps a nice start.
For Diabolos, he could gain an additional 1% for Ruinous Omen (still subject to normal resists of course) for each 100 MP spent.
-or-
2) Make it so that Astral Flow blood pacts consume level x 2 MP rather than ALL MP. In some situations, a summoner being able to use Astral Flow 4 times (with appropriate -bloodpact gear) might actually have a use. This isn't much different than a Black Mage being able to use Manafont + Manawall and pump out AoE damage as well. This might also go well with the new summoner job ability that is supposed to come out.
Thoughts or other idea?
