I get the feeling that many of the people crying here are going to regret it after they get their first couple of 50's, if SE listens and decides to nerf it.

What's the alternative, after I have 4 50's? The story is completed, the well of quests has run dry and I've run out of my allowance for leves and have to wait hours for more. Do I just que for 30+ min, and do a 30 min dungeon run for minimal exp; or do I run FATEs?

If you want to cry about something, cry about the dungeon exp yield. The FATEs are fine.
