I'm definitely in favour of a "Way of the Rogue" - I think there's a case to be made for a melee character focused on Stealth/Evasion instead of tanking.
I've thought up potential bonuses for five levels of that skill. I wouldn't mind a "Way of the Wizard" either, although I haven't many ideas about what might go into it. There's some pretty big changes coming in the next patch though.
A couple more "probably not great" ideas.
Talent:
Sure Shot - Reduces the chance of your arrows hitting friendly targets in your line of fire with the arrow (does not prevent them from taking damage from AoE effects). I'm not sure if this is possible, but it might be, since arrow FF is currently off (but will be on in next patch).
Talent:
Walk it Off - (This one is really generic and more of a vague concept.) Reduces the duration of certain negative status effects by one turn. Note: Does not reduce the duration to under 1 turn (it won't cancel a status out, you have to live with it for at least 1 turn).
