Truth be told my (biased) opinion is that the necro is one of the better roaming classes, that said..it requires you to think about your fights a bit more than other classes, once you engage you darn well win because your other option is die, your not going to be escaping. The reason that I consider it exceptional for roaming is that properly played they can dish out and take a lot more damage than you would expect (even zerker builds).
I run two builds for solo and small scale roaming. A fairly standard condi build, its mainly tweaked to my play style. I prefer soul marks as I’m often outnumbered and I tend to start swearing whenever my life force bar is empty.
I also use the signet of spite, mainly because I’m evil and enjoy the panic from my enemies. If you happen to want your enemy to have a chance, you can run something else, just change the signet trait.
Whatever you decide, play around. I change builds about every 5 minutes, so figure out what works best for you. (I prefer spite, I believe Rennoko prefers BIP)

If you like a bit more..risk..roaming on a full zerker necro is hilarious. Nothing like dropping a thief in 2 shots or lich bombing a havoc team on a ram. (I would probably suggest running the condi build till you learn necro, its more forgiving). This build is one that if your on your game wrecks everything you face, and if your not on your game…explodes. I do solo roam on this, but I tend to prefer the condi build for solo as I can’t buy a fight that’s not 1v3 or worse. The zerker builds strength is small 3-5 man group fights, especially if you have guardians or condi necros that can dive in and take focus off you. If the enemy ignores a zerker necro, they have already lost.
My guild has run 5 of these together, everybody does life transfer and you get to watch enemy groups vanish. Problem is a lot of the time nobody is left to spike when you finish >.>

Necro contrary to what everyone seems to think isn’t some ultra easy win class, it actually takes a lot of practice to deal with the various cheese builds and skilled players you may encounter. Considering I target enemy necros because their almost always a walking look bag regardless of what class I happen to be on, its obviously not as simple as people seem to think.
