I like Surge a lot with right tree, especially the relatively new Warp Unbound SG node. Warp Nexus + Warp Flurry gets fantastic value during the 10 seconds of infinite peril. Feels like a nice complement to a right side melee build since there’s a lot of crossover there in benefits for both your melee and staff.
It may well be true that Void outperforms it with the same tree, I almost never run Void so I can’t really comment on that, but I do think Surge with this setup works well against the actual game’s content, so don’t really feel like it needs a buff. TBC I’m mostly using secondary attack in this build, NOT abusing primary attack macros or any of that nonsense, and it still feels pretty damn good to me in this setup (having warp flurry maxed for like 10 straight seconds makes you shoot off secondaries FAST).
Diversifying staff primary attacks is a different matter though, as well as special attacks. I do hope they do something with that.
