I still think spawning naked should spawn you with a team uniform or something to look less silly, at least. Right now I'm using the colored tunics and the colored arena helmets with ankle boots (wrapping boots look too dirty to me). When on the purple team just use red stuff, and if the opponent is red use blue =p
Agility is important for catching the guy with the ball. As it stands right now agility has more trouble outrunning people because of the athletics nerf while carrying the ball, but their typical lack of weight sort of makes up for it and remains a pain in the ass. Forcing them to put on something they can't drop would help, I.E. uniform =p
EDIT: The nerf to throwing range helped too. I can no longer throw the ball across the map with only 12 strength, so agility has to be more careful about staying close to teammates. They are good at receiving hail mary's from a defending strength build and then moving the ball up/keeping it from the enemy while teammates move up to help. I haven't tried kicking yet, but I've seen people kick the ball across the map and it's a little annoying.
