I have exactly that path on my afflock (+1 more in perdition)... i cant give you comparison tho because it's the only path i ever had. Are you worried more about PvE or PvP? I'd imagine PvP, and cant say how much more damage that golden trait adds for you, i didnt have recount at the time. It's fine in PvP tho, or at least was the one game i played on it so far a while back.

For PvE i dont think it matters. If you like i can go kill a boss in NL and tell you what % of my damage that trait does, i have recount now.... but i dont think it parallels to PvP either way, nothing hits hard there. =/
In fact, if anyone knows of a really strong ability or artifact trait for PvP i'd love to know. Tried my destro lock tonight and was pooping out 30k chaos bolts (50k on the boss) - which was fine with the templates, just disappointing to drop from 200K outside... you know it's going to happen but you're never quite prepared.
The destro artifact ability hits OK for template-damage, but it lackluster and situational for wide-scale BG IMO. Probably good for arena. Might do 40-50% of someone's health if you popped all 3 charges at once on them. I dont really know too much on destro either, only had
that one game too and it was IoC.
