Can new players level up in the Dragon Isles exclusively?

no its a MMO centric PoV you dont go into a MMO for a story you go into a MMO for the end game. story is second and normally based around the pre designs for the end game. and there isnt any hard competition FF14 is bad unless your a DPS player and like easier mechanics, archeage is heavly unbalanced and zero story, NW is dead due to bugs and zero game with poor story, EVE has zero story and requires large amount of time just to never catch up. their is no MMO that even mildly compares to WoW they try and they fail.
