Jols, its a very good point!

We might eliminate them all together, therefore the team with most fit players is sure to win.... thats if we want uwh to be so extremly dependant on physical condition. Though this wont solve the issue of "too many bodies underwater", but it will help if combined with 5vs5 gameplay.

On a personal note...what made me love the game of UWH was teamplay and skills, not the UBER hard core apnea!
