Effects of making all "Class Skills"open?

[Ravellion]

Or, alernatively to the above system, a -1 max rank for any class that has the class listed as a cross class skill, but the penalty can be reduced by 1 by taking two class levels that do ahve the skill as cross class...

Figther3: MxR 3
Fighter3, Rogue 1: MxR 4
Fighter3, Rogue 2: MxR 6

The problem with both these sytems, especially this last one, is that you can hit a "ceiling" really quickly if you just stay 1 class.

Perhaps then, -1 Max Ranks for every 2 levels for which the skills is cross class?

Fighter 1: 4
Fighter 2: 4
Fighter 3: 5
Fighter 3, Cleric 1: 5
Fighter 3, Cleric 1, Rogue 1: 6
Fighter 3, Cleric 2, Rogue 1: 7
Fighter 3, Cleric 2, Rogue 2: 8
Fighter 3, Cleric 3, Rogue 2: 8

Hmmm.... This might work satisfactorily, and come to think of it, is pretty much what was said earlier... DOH!
