I was just wondering if there was an official policy on resting I had missed. I have previously been slapped on the wrist for resting in the middle of a protracted PvP sequence, so I thought it was a no-no. However yesterday I was involved in PvP in the Last Stand. The person I was fighting closed the door to a room which blocked the line of sight to my spell, turned me off hostile so he could rest and heal, then turned me back on hostile and came back out. Is resting supposed to represent a prolonged period? Something one could not reasonably do with hostile people banging on the door? Or is it ruled simply by the IG mechanics and nothing else?

Whilst not certain, I believe this to be an infraction. Contact a DM to discuss this further.

^What she said.

If this is a rule it's news to me, though we should definitely discuss making it one...

It's not a hard rule, but it has pretty much always been consensus.
