How well could a two man team of a sampire and a necro mage do at this spawn? Or maybe a sampire and a tamer? Anyone do this spawn often got any advice?
You could easily 1 man it... If you have the time. Problem is (like all FEL spawns) raiders will likely make all your hardwork useless... Well... useless to you
Can also depend on what shard.
Some shards, most Fel spawns are camped by someone with a stealther on a second account, ready to spot a raiding opportunity. Sometimes the stealthers are simply after the environmental drops. Others, you hardly get raided at all.
You won't know until you get hit, usually late in the spawn.
Overall though, on shards I've played, it was about 50/50. Sometime we were raided, sometimes not. Sometimes it depended if we knew the raiders or not. Usually if we knew them, they helped with the spawn. If we didn't know them, then our PvM suited characters were no match for their PvP characters.
Simply a case of suck it and see, plus don't take it personally if you get raided
The spawn itself should be pretty easy enough.
