Here's my gear and spec, gear isnt much to look at, and the spec is pretty basic too, but i can promise you it kicks ass in both pvp and pve, as long as the mob isnt immune to poison.
I have yet to see anyone live long enough for Gouge to be needed, which is good, because deadly poison would break it anyway... Envenom deals a hell of a lot more damage than Evis.
