An extra episode or two is something I'd love as well.
However, I love how they focus on only a few teams per episode and I don't think that should be changed. It's easier to understand each team's stories this way and personally it's more interesting and gripping this way. Having all the remaining teams in each episode would be confusing and lackluster. Plus, if some teams have major drama in the first days or are nearly captured, they should get all the airtime instead of showing teams that simply depart, have themselves introduced to the team of hunters, and safely hide away.
