Scout early rather than late. It's no fun try to figure out who you want to pick in the last five minutes before you have to choose.
Anyone can end up being a picker and anyone can end up at the bottom of the list.
Sometimes a team that you were barely paying attention to can end up being a really great alliance partner.
Never let a problem with another team member get in the way of both of you having a good time.
Don't take things too seriously; It's supposed to be fun.
