Well, ever since I hit Stonefalls I had the issue of running out of quests for my level. I'm totally aware of all the exploring stuff they want you to do, - and I do. Nevertheless it was a pain to get from 13 to 14, in the end I did it solely with PvP quests (... and I HATE PvP), because there simply weren't any quests anymore. I hit 14 and was happy I could finally go to Deshaan... well. I got like 3 or 4 quests for level 15, and that was about it. Next quests I got are 17+... I spent the past 2 hours riding around searching for quests (needless to say, without finding any for my level). Same story as in Stonefalls, AGAIN. After only a few quests that didn't even get me 1 level up.
I honestly feel like I spent more time running around desperately searching for quests than actually playing this game.
So what are you supposed to do in those cases? The XP from killing mobs isn't really mentionable, and I did the 3 dungeons I could do. I simply do not find any appropriate quests even after hour-long exploring. I already don't feel like logging on anymore. Constantly running out of quests is terrible, I never experienced this in any game before. And I'm only level 14. I already do quests 1-2 levels above me, and the range between my level and questlevels is constantly increasing..
