Hello, was most interested in warlord as a tree in RIFT but do not have beta access so I figured I'd ask.

Are their buffs effective?
Do they do good dps when with a dps tree?
Are they good tanks with a paladin tree?
How is their survivability?

Note these questions are all for a main specced warlord tree. Haven't really seen much talk about warlord as a main spec which is why I'm asking.
