Curious on peoples thoughts around archetype makeup in groups. I was looking at the Marshal today for example, and thinking that this class really doesn't seem suited to be a tank. Awesome as a supporting melee dps though. So if it was in the group, I would want somebody else tanking. Unless I'm balancing around something like a Necro or Geomancer familiar tanking, that means two warriors.
How locked in are folks on the one of each archtype method when running four heroes?
And on the topic of tanking, what classes do you all like for tanks (besides Knight, that one is obvious)?
