The advantage of Trueskill is that it is used to assess your rank based on your team's result, so that you cannot climb individual rank by joining high-performance teams and reaping their efforts. However, in RR3 OMP, nobody plays on a team.. so it's not actually 1v7 but 1v1v...v1, which ELO handles perfectly well by summing your rating adjustments against each individual opponent.

There are exploits for any rate of learning: use a ranking that learns too fast and you will find unskilled players earning high rankings with greater frequency.
