You will be doing that quest grind all the way to max, but the zones you get to after going to the main city and getting your house and everything are far more organized than the first big questing zone. You can stay in one area and complete the whole quest line there without having to run all over the map like it feels like you do in the first zone. The big thing is going to be, once you hit 15 you get a new adventure, dungeon, or shiphand to do every few levels so theres no point where you go a long stretch without new dungeon style content. you don't start getting anything cool for your house until after 20 really. Everything just Feels more organized and fleshed out after 20.
but if you can't bring yourself to do the questing bit and don't have a desire to level through pvp, it's probably not worth your money since dungeons willl not be viable for leveling due to how difficult they are for puggers.
