If you want to play FFXIV, feel free to do so ! There's plenty to do. Level up some Battle Classes. Maybe you'd like playing a melee character ? Maybe you'd like to tank ? It's the perfect time to try a new role, since it's pretty early in the game. Then, you could level up one of your DoL or DoH to make some gil to gear your main class ?

You can also try to get a Coils pug, and do one turn at a time ? With a good group, Turn 1 might take like one hour, then Turn 2 another hour or so. And even if you can't kill it, you can always get some practice ?
