I am never against thinking of new ideas and ways of doing things.
I do disagree the end drain is pointless, having played and again am playing several electric characters, Storm/Elec Defender, Elec/Elec Dominator, Elec/Elec Stalker, etc the drain may not substantially and consistently affects mobs - no more so then the defuff from a Peach Bringer, Warshade or most other damage types, it does make a big difference for the attacker. All those chances to get end back add up and characters heavy into electric last much longer in a fight. With a couple choice end mods (for the powers that take them) you can do without Stamina and the costly IO for procing +end.
