I made a Trapping set for my ranger, consisting of Radiant armor with a Sup WS on the headpiece, Sup Expertise on the chestpiece and Attunement runes on everything else. Combine that with a +20 energy staff = 59 or slightly more energy. (As opposed to the previous standard of 47)
[Edit] It seems I lie. 59 energy is max if I put on both a WS and Exp rune.

For most of my characters I wear 2 sup runes and a vigor rune. generally just a major vig because I just can't justify spending all the extra money for 9 health points. This leaves me with 2 open spots. For my monks I prefer the vitae runes, which i put on my hands an feet. i have (or will have eventually) maj divine fav on my legs, maj vig on chest and headpieces with sup rune for each heal, prot, and smite.
As for my other chars, more than likely they will end up with vitae runes as well. I have not found a use for the attunement runes simply because 2 energy each doesnt seem worth it to me. thats not even enough to cast one spell. i think attunement runes as they are, are relatively useless. perhaps i woudl use them if they added say, 5 energy each.
as for the condition runes, haven't looked at those at all yet.

I prefer the Vitae runes myself. 2 energy doesn't affect my ele one bit. (e-management pro
