There is no better solo class in the game, over a necro. FD pulling, snare, root, have a tank(pet), do top dps, can self heal, instant invis, great mana regen. If it doesn't summon, it's dead lol. Even if it does summon, just pet tank it.
I think, there was another. Too long ago. Mostly it is the 3+ player requirements NPCs say my level 121 and his dirty merc can handle a level 30 quest. MOBs so bad I need a group But then I'm not playing as intended. Call me anti-social
