i don't really want anything in prot aside from a Spell Absorb or Spell Reflect ability. why Add things to prot when it's already bloated.
as for a talent in Ret... I've always wanted something like:
Come Into the Light (coolest thing i could think of off top of my head lol)
Pulls the Target to the caster who is filled with light and Blinds the target, causing it to wander disoriented for up to 3 sec. Any damage caused will remove the effect.
it's like those Engineers in Nagrand that pull you in with a hook. no a charge but similar end result.
