Offensive and defensive, yes. These are my scores from the competition matches this season: 3-1, 3-0, 4-0, 4-2, 8-0, 4-1, 5-0. Scoring is way up, goals conceded are low. But this a new thing this season. Last season was up and down with the same bonuses.
Possession, maybe. Hard to gauge. I always have a favorable possession ratio, but this can be due to any number of reasons. Training bonus could be one of them.
Condition, I don't think so. My squad is just as tired after a match as they used to be. Perhaps if I did not have a 10% Condition bonus, they would get more tired than they used to. I am not going to find out.
Now why are some of you saying you have to be present at the match to activate the bonuses? Is this official? You are not confusing activation with boosting? I expect I am getting 10% bonus across the board and I get to boost one of those to 15% if I am watching. I usually boost Attack the first two times, Possession or Condition afterwards (assuming I am up by two).
