To me it seems like there's almost no point in doing dungeons to level unless you REALLY despise questing. I find it ridiculous that they made dungeons almost useless in my eyes. On my new warlock, whom I am in the process of leveling, I did Wailing Caverns at level 16-18 or something like that. I picked up 3 quests inside Wailing Caverns and I want to say it took us.. about 1 hour to 1 1/2 hours and I got the exp from the dungeon plus the quests. I wasn't too bothered at first that I only got 1500 exp from each of the dungeon quests... Until I went outside of the dungeon, completed a quest that wasn't an ending quest or anything, it was just a normal collection quest, and got 2000 exp.
Does anyone else feel like there's almost no point in doing dungeons now that they nerfed the quests to hell? In my opinion half the reason you do a dungeon is to do the quests because they gave massive amounts of exp. Now I feel like there's no point because I could continue on doing my easy quests and getting 500 more exp per quest rather then waste my time in the dungeon queues only to perhaps get a terrible group and lackluster exp.
I do realize half the reason you do dungeons is to get gear, but with they speed at which toons level with heirlooms the gear you get from dungeon and dungeon quests aren't that much better then the regular gear and they aren't really worth the time.
TL;DR - Dungeon Quests give 1500 exp at ~ level 18 and regular quests give about 2000 exp.
I might be the only one experiencing this but it just seems odd. I can understand them nerfing them because before hand it was like 5000 exp per quest for the dead mines quests...
