D&D 4E Anybody for Wheel of Time 4e?

[Garthanos]

Effectively, channelers should have class build options to pick their secondary role (leader or striker, on top of controller, or possibly leader or controller on top of striker).

Thematically, they should also have class build options to differentiate between inborn or trained, and what type of training.

It can work as differing class features avialable for selection for instance
Weapon proficiency and leather armor being relatively common amongst the Wilders? Hey the wilder really could be just somebody multi-classing.

Though it might be more 4e like if the sword wielding Ashaman who sometimes rains fire on his enemies or pulls earth grenades from the ground is a different class than the wind weaving healer Aes Sedai, who has a nice capturing attack using air.
it isnt always different powers that make the difference though.
Example Power differences between the two here is an example for teleport... In general in story the high level aes sedai creates a sameness between two locations which she can sustain and the ashaman rips a whole in reality that takes a while to seal but spends the effort to make it last initially. Similar - but not identical effects.

A Weave could have Ashaman or Aes Sedai *(Saidar / Saidin) rider description on its effects to differentiate.

The PC's aka Ta'Veren seem to have work arounds so there Aes Sedai didnt have to be oathbound.
