What's good about this game?

The story vastly improves once you get past the current section, takes a dip for the worse in the 2.3-2.4 section, then ramps up well in to Heavensward. There's less "run here to talk to x and report back" and pointless fetch quests the further you go.

The fights get more complex and exciting the further you go. Once you hit 50 there will be a ton of content you can do - namely EX primals of the ones you're fighting in the story now- that will give you a taste of what end-game is like. 24 man raids and Coil will also open up. Your job likely won't feel "complete" until you get to level 60 or so, but there will be more for you to do during fights at least. Note that this applies to old end-game content and not necessarily to dungeons and story stuff.

Dungeon queue times for DPS never change much, though you might find your queue times decrease a little the more dungeons you can be thrown into. Generally speaking if you want a fast queue as DPS you go with a tank/healer friend. Queuing in progress might shorten it a bit too if you don't mind joining a run mid-way.

I'd say if you get through ARR and aren't liking the game, you've given it a fair try. As good as the story gets in HW, as fun as some of the fights are, the game isn't for everyone. And they put a jump potion on the Mog Station for a reason... easier to accept cash to skip the worst parts of the game than go back and fix them.
