I only change it if I'm losing or a draw...
Usually I'm playing normal. If losing then -> Attacking.
If leading, I'll keep it on normal. No need to change.
Same with the bonuses. If I start a match -> Possession. If losing -> Attacking. ( same with the draw ) and when leading, then defence or condition...

// ( Sometimes, when I'm winning with 3+ goals, then I also hit attacking to get more goals...)
