Things to do

- [x] Handle balancing differently by selecting players based on their strength/weakness
- [ ] ~~Punish players who move the enemy team flag closer to their base when it's unfair~~
- [ ] Punish players who hold on to the enemy flag for too long when teams are unfair
- [x] Exclude observers when counting players for the selection process
- [x] Only swap players on death
- [ ] Fix balancer to only announce and do calculations to balance once
- [ ] Figure out a better way to balance if a player takes too long to die and the balance takes forever
- [ ] Keep track of players who got swapped and when, so don't swap them often
