While I haven't played nearly as long as you, I too love Enhancement more than every other spec in the game.
More on topic though, what I think might be good for us in pvp at least, is making Primal Strike an actually useful ability by severing it's shared cd with SS and make it usable after one of our SS's or LL's get dodged/parried. That way losing the damage from a missed strike won't be as punishing as it is now and PS will actually be something different than clutter in our spellbook. Buff/nerf it's damage accordingly and also make it unable to be dodged/parried just like overpower. In my opinion it doesn't need anything else, but right now losing damage from a dodged/parried LL or SS is huge and unnecessarily punishing.
Also, to be fair, this is not my idea but something I read once, maybe even back in Cata or before.
