I don't know if exemplar is a consideration in this build but in EA in general the End management stuff comes in the 30's thus the health +rec stuff really seems to help in lower level TFs, etc. Plus I don't want to rely on the clicks most the time.
In my build I only use Energy Drain to cap Fire/cold (2 enemies maybe?) and Neg Energy (a lot of them, lol), usually it sits there as a LOTG mule.
