Uses for Skratti?

I did find a creative use for the Werewolf (or wolf?) aspect of Skrattis. My mage form of Skratti was marked with old age. I noticed that he wasn't 'old' in the other two forms. Every year I changed his form the turn before the age afflictions kicked in and he never sufferred any old age afflictions.

Well if you're doing a change form back and forth every year that's two turns of research for one unit. So if you're doing change form for 20 of these back and forth that's 20 units not researching for two turns... thus if one provides 7 research then you're losing 140 research points each year.
It's probably better to take a growth scale then to do the micro_management of changing forms and losing research.
