So I am flying around questing and I happen upon a PLD and SAM who have decided to solo take on Agrippa the Mighty - I was under the impression it was not going well as their health bars were pretty low.

Rather than jump in as the DRG I was at the moment I switched to RDM as he can of course heal. Heals were provided and them the PLD was reduced to a jam like residue on the floor by a massive AoE I assume they overlooked. Swiftest and Verraise amounted to a vanished PLD - they probably had sense.

I decided to soldier on and help out by throwing out heals and damage but was confused to have the SAM scream at me to INTERRUPT OMG - excuse me? Interrupt what and with what pray tell?

I am unaware of a holy grail ability of any RDM to interrupt and render senseless an S rank elite or was this just another example of someone who tried to help out getting the "blame".
