Me as... Necro (SS/Curses):
1. Olias (MM)
2. Jin (Barrage/Splinter/Pet)
3. Margrid (Barrage/Splinter/Pet)
Sometimes Pyre, I like to use him vs Charr.

As a Warrior (Axe most of the time):
1. Master of Whispers (SS/Curses)
2. Olias (MM)
3. Pyre (White Moa + Splinter-Barrage, also great if you use an axe)
or Livia as N/Rt Healer for 4 man areas (OMG, is it a SABWAY?)
In general, Necros are on top of the PvE Food Chain! Quite ironic how bad they are in PvP. They are almost the opposite of Mesmers.
And they already PWNED before Sab brought the light of knowledge to the ignorants of this forum! (lol)
