This is one of the easiest MMO's to level to max level solo I have ever played. I don't get how anyone is having issues with it, or think it's hard.
My friend got 1 character to 50, one to 41, and several into the 20's in the first 30 days of launch...
I got to 50, and 4 up into the 20's...
This game is not hard at all. In fact I wish it was more like the original EQ when it comes to the speed you level at.
