Guys,
I see this done all the time and it's been mentioned before but I think it bears mentioning once again.
You should only claim the entire dungeon/raid if you COMPLETED the ENTIRE dungeon/raid. Otherwise, just claim the bosses that you killed. The intention is to give you an extra bonus for finishing a dungeon/raid and not for just attempting it.
Even if you kill no bosses, you still get some honor points (5) if you post the event. But you're not supposed to get 50+ honor points for attempting a dungeon/raid.
I know it's a honest mistake and normally I would not even mention it but it's being done quite repeatedly now so it probably needs to be addressed.
