another point on mutates

[Wright Frazier <khelek@ns1.cioe.com>]

Since you now have to pay for mutations with xp, does it still
mean you have to do multiple mutates to get ranks in the ability?
i.e. you want to go from rank 1 exa agi to rank 2.  Do you need
	to get 2 more mutates AND blow 10K or so xp(I don't remember
	the exact cost).
Or now do you just get 1 mutate and blow the 10K xp?  Also I've seen
in the past, and recently, characters continuing to buy up mutated
things, one that sticks out in my mind currently is a character who
bought up to rank 12 fly.  

So I guess the question is, should such a person require 78 mutates
and 15,600 xp.  Should it take 1 mutate and 15,600xp?  or should
it take 12 mutates and 15,600xp?
