I played when the game released, got to around level 50 and quit.
I'm bored and now that I have found out there are 10 man raids I want to pick this game up again.
I don't want to buy heart of thorns until I'm closer to max level out of fear that I may not stick with the game long enough to hit max level.
If I don't buy Heart of Throns right away will I be missing anything out of the game?
