Take as much time as you need. Rushing it won't help anyone and neither will overwork or stress. I am personally in the waiting camp, lurking to see when the game is fully out, as I know that my will to play and grind again will crumble if all my progress gets wiped multiple times.
I wonder why people treat this as some kind of a paid service, which needs to have a large userbase to make money? As far as i understand, this is your pet project and the amount of users probably won't make much of a difference to you, at least financially. Whether people wait or not is mostly irrelevant.
