a good sub-class for a necro ?

just want to get some suggestion from you experts before I go oops. I am playing a necromancer atm, wonderring which class should I get for subclass ?

prefer mage class because I dont wanna keep two sets of armors/weapons and switch back and forth...

thank you !!

Dunno why you'd want another mage if you already have one but SH then I guess.

If you want to get noblesse as fast as possible with the same gear as your necro... go SH.

You could also try a WC or Healer if you dont want to be nuker but still use the same gear.

If you want to rush to Noblesse SH sounds like the best. Non-stop solo is very consistent.

Or you could play a healer and when you cant find a party just go back on your necro and solo. Pole groups are really good exp. and they can always use a healer.

Also a good buffer could be nice esp. if you want to lvl a Wind Strider with you. Having a high lvl Wind Strider when you become a Nobless if a real nice thing to have for seiges.
However this would be rather slow; maybe better for your 2nd sub.
