I guess that depends on what is draining you. Energy Siphon seems to be resisted, as does BTSx, Tyken's Rift and Polaron Procs. Siphon Drones, on the other hand, are either not resisted or drain so much it doesn't matter. It's really hard to tell since everything hits 0.
i'm not under an any ilussion im going to get o power drain because iu have 9 points in it i was asking a question if anyone else had mixed results i was intrested to see if people were having the same problem with energy syphone drones
