I don't. In fact, since Accumulate costs so much more than all the other Squire abilities, and I usually ditch that class about halfway through Chapter 1, I don't usually get around to learning it until before Riovanes Castle. But then, Ramza's just gonna learn Scream a couple battles later, so that's no good for poor Accumulate. =( If I didn't like Gained JP Up and Move+1 and Throw Stone and Yell so much better, though, I'd probably get it earlier.
