I know some Bronze players that are my age (25) that just cannot get their head around the game. But they usually have minimal RTS experience, and have a ton of trouble multi-tasking in the game.
I myself had a lot of RTS experience, but never anything serious. I wasn't even aware of iCCup till just 2 years ago, and never played on it. And I am one of those players sitting in high diamond more or less, though I think a lot of that has to do with basically not playing on ladder for months on end before and after they introduced Master's league.
But I've played mid-Masters players that will, say, drop 32 marines at my third (one with rocks) on Delta and have them get destroyed by Colossi, doing almost no damage. And then that player pushes my front door with almost half the supply and just gets destroyed. Though I guess it is just the game evolving, since for months after release it was a lot of 1 base heavy play, where an expansion was delayed for a while. Now it seems to be moving towards 2 base play with a lot of people being awkward on taking a third.
And the rankings don't mean that much in my mind, since they aren't that selective. Being in GrandMaster will mean something though when they open it up, being only the top 200 players. But the skill gap in Masters is just hilarious, much like the difference between a Bronze player and a Diamond player.
