there is a difference between gameplay and training.
I would love to train to be deadly and have a team and kick some ass with them, but the truth is that the people that are trained or 'in training' are not doing the same thing than people trying to have good gameplay and a good time.
for instance, take a CQB facility full of paintball greasy sand and put in a mix of tactical teams and skirmishers, the TT guys are going to complain all the time
In the same facility, a game with only TTs is going to be a completely different deal, just as a 100% skirmish game.
I must admit that the games I've had the most fun ever were Silverthorn's Zombie games, and they are 100% not tactical: the ambiance is very happy and the action is intense.
