Necros are not ONE of the best soloers... We ARE the best. Before you get Tainted Heals with AAs you are king of soloers.. After that - you are God. There is no such class in the game that can solo as well as we, necros. Yes, many CAN solo good, and you can compare soloability between, let's say, Brigand and Templar, but you can't compare Necros with others.
I sometimes forget about that and when people ask in guild or ooc "is ^^ soloable?" I usually answer - yep, easy. And then having that person complaining about failure and how I lied.
