Ok, so we have all heard why Ether lord should be ripped from the Mesmer list, scalded with Acid, and thrown onto a highway right? It's an energy tap that can only be cast on low energy, gives less energy, and takes time to recieve the effect. Boy is that a pile of crap, or is it......
Ok, enough with the cheesy suspence. Basically, I just think people are looking at the skill wrong. You don't use Lord for the energy gain, you use it for what it can do to someone who has just been drained of all their energy. If cast directly after draining, it will lock that player down so that they will be unable to reach 5 energy for the duration of the spell. This is desierable, since once at 5 energy many casters can use an energy regen spell or glyph to get themselves back up to speed, which you don't want. So if lord is cast correctly the opponent will be at about three energy when the spell ends. Including the time needed to get to 5 energy from there, their total lockdown time comes to about 11 seconds. Or you could time an ether feast to hit them when at 4 energy (this is after Lord has ended), increasing their down time to more like 15 seconds. And all of this would only cost you 1-2 energy. (this is not including the initial draining, just the extended lockdown period)
In an energy denial build, I thnk this would be useful. It pays for itself, letting you spend your energy on other things, and Ether Feast is probably going to (or at least should) be there anyway, so the whole thing is only taking up one skill slot.
