think there should be a higher incentive for nicer players. just a +1 medic pack wont be enough to persuade evil players to play easy. i had 2 injuries against this one team, and after i looked through his play record, he has injured an average of 3 players a match. so my suggestions this;
what if you get 2 med packs if you set the tackle on easy, 1 on normal, 0 on hard, and as an added bonus, +1 for a clean sheet. changing the setting during game play wont trigger the bonuses. last but not least, AI teams are on easy tackle. win win right?

hoping othersll agree since i hate the injury system as much as you guys.
