It's hilarious that people consider 1400-1600 "mid" elo. Guinsoo has stated that the top third of players are 1200 and above, and that's roughly 65,000 players considering the ladder only shows people above 1200 elo (about 2600 pages x 25 people a page).

There's roughly only 250 players above 1800 rating, which is about 0.1% of players that are rated. There's about 1250 players between 1600-1800 rating, which is 0.6% of ranked players. So I guess people think only 0.7% of players are good enough to be of "high" elo, or above 1600. Good times.
