Soul Driver + SE = BROKEN WHEE!

ACB is without a doubt the same speed as power strike without FA.

Blast is incredibly slow, though.

Plus I'm a BW pally, so my range is all over the place. I think my min on holy weak is around 15k while my max is almost if not over 50k, with acb.

EDIT : As for rush. BW pally, rush always stabs, and I can still hit ~7k-9k (not sure) with it on holy weak enemies, so yes, it makes a huge difference. Level 1 rush.
