You left out ele. I just have a GS mesmer from what classes you mentioned, but if I were to ever bother to unlock a 6th slot I’d go with ele. If necro could use a bow, like how they could in gw1, I’d already have a necro with an identity crisis. But they don’t so I wont. Mesmer isn’t too bad, they do have stealth to keep them alive. Mine doesn’t die too often with high vitality.
