Ss, Sv, Mm?

Ok so i only have factions and right now i have an ele, rit, and monk. I'm thinking of making a necromancer..but since i can't get SS im not so sure anymore. I know i would be able to cap SV, which is what i plan on doing, but is it worth it or should i just go MM?
Thanks so much

You know, it's not like you can't do both.

My necro (that has been sitting in my char slots for 14 months) which I just started playing again before yesterday, I find that for PvE almost any build works. Personnaly I'm no fan of MMing.. For starters, heroes do it better. Being a curse necro is alot more fun IMO and even with just SV and factions, you can make a decent build. Btw... If I happen to be in a PuG, which I don't often, I ask my team what they want me to do, in some areas where there are many corpses MM is best, but if your fighting un-fleshy foes, go blood or curses. You can even be a hybrid if you just cant find enough skills. Use SV as your elite, Max blood, Max curses and put the rest on soulreaping. Or you could use an elite skill like SoulBind (spammable knockdowns are quite funny) and use a mesmer second proffesion to gain a few extra hexes. The world is full of opportunities, do what you like to do.
