It shouldn't be too bad after the update even without barlight and bardark... Increased resistance from runes, Even if it only goes up to 35 at level 99, it's still over 100*, and I could see it going to either 40 or 50. Then with the reduction in recast timer for Valliance, the reduction of Vallation is irrelevant. Valliance > wait 3 mins > Vallation > wait 2 mins > Valliance etc, rinse and repeat. You always have one or the other up for vastly increased damage reduction.
I just wish I understood exactly what their effects are!
Edit: * with 3 runes up
