I was saying having a semi-permanent evolution pool(set after an extended rest). and an enraged pool(accesseed and alocated every time they hulked out which could only be done a few times per day).
So with your proposed system they get more and more freaky until they sleep and turn back to normal? or do the evolutions have a duration?
BTW the reason i'm so interested in this thread is, i was developing a simular class that evolved when enraged, but took damage proportional to the EP spent on the rage at the end of the rage.
Also summoners and Edilons are awsome
