I THINk it's only different in that it counts as provoked, like a guy not needing a va to try and save his wife from some slavers. Not entirely sure, though. Dont quote me on this.
I personnaly think it should apply to raid rules, I have been in the 20 man party to save someone before and we steam rolled them, it wasn't fun at all. It makes zero sense for raid rules to just not apply anymore like that :/
