Tales and Chronicles
Jewel of the North, formerly know as vincegetorix
I do really like this idea, and if something like this were adopted then my objection to subclasses being gained at level 1 no longer applies.
This is already how I do it for my more casual players since I need to accompany them at level ups. So unless specified, all classes have a pretty straight progression. Especially so when I dont play with ASI or Feats.
