The main issue with a channeling based build for EB is that when a wave goes out it drains energy every time it hits a target, so if you throw a wave into a group of 20 enemies that's channeled, regardless how efficcient you are, you're going to run out of energy very quickly, which will deactivate Exalted blade.

Your best bet is just to build for a burst channel, such as Life strike, since you can proc it several times with one swing. Only use it when you NEED HP, and you'll get it all back. What I do personally is use a finisher berserker build, with Life Strike. Essentially, you get low hp and you pop Radial Blind, channel, then finish one target, you have all your hp back, and keep cutting. Only costs 10 energy for me, so it works out well with rage as well. Making a VERY tanky excalibur, with high ability availability. (Since I use Efficiency builds on every frame.)
