I kind of feel like they missed an opportunity for xenon.

I mean I think the bigger issue is that Energy Surplus gives %-stat, which deincentivizes (is that a word?) poorer and less funded players from using it unless they can bump it back up immediately. To me it also reads as Nexon being like "we need something for Energy that isn't just a buff" and then coming up with that.

Putting it with Triangulation would be kinda cool though, given that Triangulation isn't much of a happening skill on its own either.
