It looks like it's gonna get lower once the current top teams will get old in 2-3 seasons.
Anyone who is in D, C or B right now, with at least 1.5 billion in their bank account and a few young players that can play 74+ at 100 exp, should be planning to fight for the title in season 117 Once me_dinamo and Adjud's players get old, the path will be clear. I don't see any superteams coming from behind, ready to play 153-154 and dominate A. The only teams with potential that i've seen so far are Eendracht Aalst, Er2c and Sokol Dubidze, but neither looks yet ready to dominate and who knows how much budget they still have.
So seasons 117-118 might be one of the best windows of opportunity for aggressive teams to finally get a title (wink-wink @Ben, @Charlie ).
