I dunno if it is just me, but I rarely play attack mentality. Even against a totally wank team, when I play attack mentality, they seem to get a lot of chances.

Also, I find too many games where there is a deadlock for a long time then one team capitulate (run out of energy?) late on. This is specially true against bot teams where there was a game earlier on and they are playing with low energy players and I have a full energy team.
