I play a paladin, and I'd like to know a few things.

First, one of my party members told me to stay still so I wouldn't slow the DPSes down. Would anybody else recommend this, or include when you're avoiding AoE attacks? (The latter doesn't include AoE attacks that will kill you, like one of Titan's)

Second, I should prioritize VIT and Parry, right?

And thirdly, when people say "use Flash more", does that mean using Flash at the beginning of the fight to rack up enmity, or actually use Flash when the aggro is away from you?
