I am glad there are more people noticing this bug / nerf / "fix", because 30% less XP it's definitely our new reality now. I was hoping somebody from the staff could comment on it.
To guy who said "Doesn't seem like a really big deal..." - well, being one third short of the entire questing experience (in Vanilla, at that) equals to literally grinding mobs for the last 3 levels or so. While it's not much of a "problem", it certainly shouldn't be the case - in my opinion.
Because it never was, before this change took place. I guess we have to adapt to it, but I'd still appreciate to hear if this was intended or not.
