ok... Ok but are the quests repeatable? When I have started my last few characters I go to every zone and do the quests until all the quests are complete. Which is usually enough Exp to take me to the next tier zones. That said I would like maybe more quests in the zone matching all the way to level say 10 or 15, or making the newbie quests, then say require level 10 for the next quests in said zone which makes the quest red and mobs required for the quest not spawn until they are yellow con. if you get my jest. Repeatable quests may fix the jumping around though.
that's just my 2 pennies.
