Where does the rating come from? If all good/active teams would have played against each other on a regular bases, and there are only like 5 of them, noone would have gotten significat more rating. Their rating gain results from farming low teams directly, because the 1,5-1,9k rating teams are like completely missing. The main problem remains that there are not even 10 active teams going for ranks to begin with. Even if these teams played against each other all day long, its still just a team-pool of 10 teams. This way the titles mean nothing in the end. On retail it made more sense, because the realmpools were active and gladiator was like 2,7k rating needed. These numbers were created by player activity.
There is a difference between "the best of 2000 active teams" or "the best of 10 active teams".
