Not sure why no one is asking questions since you're so kindly offering answers — I'll be the first to ask a couple of general questions then!
1) I can understand that certain boss fights benefit much more from certain niche utilities — what are two generally good utility point setups for 1) flashpoints and 2) story content?
2) What is the general single target and AoE opener and rotation (or priority)?
I play an Immortal Juggernaut; also a returning player.
