Ah, but you misunderstand. Giving new content the top 10% of players would enjoy wouldn't make them enough money from the bottom 90%.
I consider myself a experienced(not neccicarly good) player. I recently checked my rankings and even i am only in the top 25%.
Even for other experienced players(that make bytro more money then the best of the best) wouldn't get to enjoy this new content to its fullest. It just doesnt appeal to a critical mass for it to be considered.
Bytro adding content just for thier most loyal players to enjoy? Unheard of.
I like the concept though.
