I have no incentive to play ladder for the following reasons. 1 - It has not been reset for ages, unless you are able to play the game 24/7 you have very little chance to get to the top 100. 2 - Found Match and other bugs, just annoying that CA will not fix them, 3 - Poor design. The system they use is not great, it promotes draw kitting, if it was more like the FFA system there would be no point to draw kite as if you are behind in points you would lose by default. Also even if you lose and do well you could get good points. Ranking would be bassed on average points over a number of games.
Even a basic reset would give me least some incentive to play QB.
