Mmm. You just let the birdie out.
So dragons are not balanced and need a change? I assume there is a sketch of a plan already.
Let's see, imho:
Dragons = strong melee, weak casters, weak crafters, lairs are a major pita.
Hopefully "more balanced" doesn't mean bringing their attributes in line by altering the strong component and making them: weak, weak, weak, pita.
I guess this is another discussion anyway, but thanks for the heads up.
