I find Guild Wars 2 leveling a bit more tedious than other MMOs due to volume of ACTION COMBAT RAWR and the speed of travel. The only two major MMOs I feel have worse leveling are Rift and like FF14 v.1. Not sure its fair to mention XIV, because Yoshi P. is my homedog now. But goodness gracious is MMO leveling generally boring.
Really enjoyed SWTOR, TSW and recently Neverwinter leveling. In Neverwinter I got to like level 30 or so before it noticed "Oh, this is how they do questing". Neverwinter felt very GW1 to me in leveling style in that you are basically running a series of interconnected missions. Each of which is nicely compact yet can be run at a fiarly brisk pace.
GW1/TSW do it so very right.
The perception of leveling in GW2 is likely different from reality though. I admit. It's just a far more transparently repetitious game in the "questing" scheme.
Say no to levels in all MMOs. We need to be done with this shit as a genre.
