The game devs want you to play the game more. Therefore, I do not think it is unreasonable for them to place a reward after you do well in a certain high number of games.
Also, regarding the tournament, the rules of the Battlethon event state that you must earn "50 gold medals for damage." Consequently, you can not earn progress in the tournament because there are no metals for tournaments, only metals for kills and assists.
Please understand that the devs are not going to hand out 700 a-coins to everyone. It is a reward, for those who wish to invest their time into the game.
I certainly do not think this game is "turning to crap"... not yet anyway ;)
