So, basically, in the upcoming updates we should see the elimination of the servers as a barriers for the match making.
A level 2 will meet level 2 teams from any server, same at any level, and this means that there will be a real availability of similar AvQ opponents
Too, as has been commented here, the top server levels should have finally a solution so to promote constantly without problems.
We need to stay tuned just a bit more, but It will/should change the ambient for good.
