I'd want it to go a pretty decent speed, but if you're worried about slowing it down there is options if you're really interested. It could be possible for you to play a character separate from the main group that works with the group. That way if you know you're going to be super busy you can split away from the group doing something else. It's entirely up to you how you'd like to do this and I'm here to help figure it out.
