Yes, it takes a lot of XP to level EDs.
No, running the same quest 10000 times over and over again is not my cup-of-tea.
Yes, it is a slap in the face.
Just because I do not like running any one quest over and over again, as in back to back to back, ect... I do like having quick quest that I can run to get good XP when I have nothing else going on. So yes I have ran Rusted Blades many times, nowhere as much as someone who is ED XP capped but a bunch.
As Cyr said, there are other quests out there that can be done as quick as this one, and people wanting to farm for XP will just switch to them, but what happens when Turbine does the same thing to those quests? Sooner or later, unless you play 24/7 it will take years to get your toon capped, there has to be a medium between capping in a week-end and capping sometime in 2015.
Oh and signed of raising the challenge XP back up, please Turbine give me some sort of reason to run them.
