quests in dugeons

like other official blizzard patches i feel like having the dungeon quests at the start of the dungeon and not at the entrance would help players with getting more XP from them. Most of the quests are defeating bosses or mobs so that helps players get XP faster. Sure you can ask for someone to share the quest or het it at the entrance i feel like it would be easier to have them in the beginning of the dungeon

If you're referring to wotlk then it's not possible, it's something that was introduced with cata I think.
