I agree completely with Mihazi.
SST, CS1 & 2, Dwellings - All go. You are starting over as a character!
I think donation points, avs, any donation points put into forest fight or turns, custom weapons, etc. should all stay.
Also, there would have to be HEAVY incentive to switch, right?
I mean, I know there has been talk about making sure it is not "overpowered", but I want it to be worth the sacrifice.
Oh, and I like Mihazi's idea of 2 DK points per DK (at least for the first few).
