If you have an interest in taking part then paying for a subscription would ideally be your way of showing you appreciate the fact FlyOrDie even hosts subscriber only Tournaments.
If there we to be more FREE to play Tournaments it would cause more trouble than anything. People would be point banking off of multiple accounts all the time since it wouldn't require a subscription to take part. This was a MAJOR issue in FlyOrDie years ago and probably still is on some games.
I can see the good out of there being more free ones..as not everyone can purchase subscriptions but it would only bring more negatives than positives unfortunately as that's how a lot of users tend to play games on here. Every game has bankers...
