How do you chose your opponent?

I voted "I play my friends only, to support them", but I'm actually doing a bit of the others depending on the situation.

- I play to win no matter what!
No. I play to win to get the first-win-of-the day. I play to win with my 5-star team. I play to win to use tonic.

- I play to lose to a 5 star (more AB)
Did this mostly in the beginning, and still with my less than 3.5 teams, unless using tonic.

- I play my friends only, to support them
Yes!

- Revenge!!!!
Easy way to reciprocate with friends. But I don't do just this.

- Random opponent
No.

- Single Player
At the begging that was all I could do. Still at that point in my RTTF competition game. :)
