I loved the idea of iconic classes - the penalty itself was just far too harsh in my opinion. In fact I always thought it should have been a bonus [which would be hard to work in] rather then a penalty.
Upon later consideration I concluded that losing 1 die would have been sufficient to be a legitimate -1 drawback.
It creates a choice where you either~
Suffer -1 starting action dice (totaly solid as a -1 penalty)
Effectively gain 1 design point for playing heavily to one of 2 classes.
Oh well. You never stop learning.
