Do ads give XP in Prae and Castrum?

So I've heard that the ads do not give XP for these dungeons, just the bosses, but recently someone told me you get the XP from the adds after you kill boss. Instead of giving the XP out as you kill them you just get a lump sum after the boss. I suppose it would make sense for the ads not to give XP so they can give a set amount of XP rewarded at the end but seems silly at the same time to me. Does anyone know if there is any truth to this(with any proof available)?

I believe this comes from the Patch 6.0 Notes:

> Experience points previously earned from standard dungeon enemies will now be earned from dungeon bosses.
