Just got finished playing this. I was supposed to be in bed 3 hours ago damnit, I hope I don't miss work...
Just so everyone knows beforehand, I have little to no knowledge of football/soccer or whatever similar sports there happen to be. Additionally, I was playing my character with 27 agility, 12 strength, 9 athletics, and 4 power strike and wearing light armor (fur hat/coat/hide boots/mail gauntlets).
I tried my best to stay open and use my teammates to get around enemies (run at enemy and they run at you, retreat behind a teammate and they will ignore said teammate trying to get to you, leaving them open for pummeling as you continue on). One time it was a huge melee fest on the football map (I'm just going to call it football, despite being from NA) at the enemy goal and I had the ball. There weren't any real viable passing options since everybody was fighting, so I weaved through the battle and scored a goal through everybody. Wish I had it on video. We still lost the game, unfortunately, but that kind of stuff is pretty sweet and memorable.
I'm all for additional "jerseys" being added to the game. Currently we already have colored tunics over mail and surcoats over mail. I don't quite know about changing weapons. Perhaps have a set of a couple weapons to choose from. If people are going to be able to wear heavy armor the weapons need to be able to reflect that. Also, people going naked would be annoying, so there would have to be a way to force them to wear something.
The way I see 'dying' is the enemy knocks you onto your ass and you need to take a few seconds to recover. It would be nice if attacking someone who has just recovered (with invulnerability) gives you a penalty of some kind, like giving you a weight that pretty much immobilizes you and makes your swings slow for a few seconds. I dunno, just throwing ideas out. Teammates shouldn't be able to spawn on top of the enemy goal, though.
Goals also definitely need to be marked in some way...
