They cannot use TruSkill.

TruSkill was developed and is owned by Microsoft.

FMEA≠Microsoft∴Licensing Fee.

In order to use TruSkill FMEA would need to pay a licensing fee to Microsoft, that is assuming that Microsoft would even be willing to let a major competitor use their system.

What happens when FMEA pays licensing fees? We pay more to play the game.

Ranking systems are not a trivial problem. I have spent a lot of time chatting with Matt Edmondson about this, and he spends even more time thinking through how he can make the OMP ranking and reward system better. Some very, very smart people came up with Elo and TruSkill and it isn't something that you can sit down and improve on in a day.
