The Regen Necro
Love the idea.
Needs more Siphon.
I got a fever, and the only cure is more Siphon!
As for real advice, I’d say try to work Siphoning Wells in there. I wouldn’t go with ALL wells, but at least one or 2 would help for when you get outnumbered.
Also, I think Dwayna’s runes are overkill since we can get regen whenever we need it from weapon skills. I’ve been playing around with Earth/Grove rune set for extra Protection up-time, mostly to ramp up healing/siphon efficiency. It works fairly well, but I haven’t really run it through it’s paces. Also, I’m terrible at WvW so that makes testing builds a huge challenge.
