I run these two ele builds and I haven't seen them in your guide or in the pending modifications:
The Ether Prism Healer works well in areas with a lot of enchantment removal and when you don't want to dedicate a necro to healing (N/Rt healer is more reliable imho).
The Ward Against Harm ele shines in areas with a lot of fire AoE (Sacnoth Valley, Kathandrax Dungeon, Fire Forest in FoW, etc) but is good everywhere else since heroes tend to clump together at all times. I've put a lot of energy management here, not all will be necessary depending on the rest of the bar (could be /Me for a different kind of e-management). No wards are in meta because they're not that helpful when you have targeted prots, weapon of warding, etc. Only good ward is Ward of Stability for Jotun dungeon.
Ether Prism is ok, but really; in areas with enchant removal, I would micro my ER hero to cover ench itself. If it's heavy enchant removal, take Dunkoro. he pro. Taking two spirits on one bar is pointless when you're probably using a SoS rit too. You can give them Rt/Me for rupt e-management, etc.

/Me e-manaagement is all good, but what happens when you face W/R/P mobs?
