I disagree with you both. System's defects should be pointed out at any cost. Last days was organized big questionnaire about future changes in ladders. I haven't seen any changes in ranking system.
Two wrongs don't make a right, and an eye for an eye, leaves the world blind.
You gamed the system when there were those around you who didn't. The system is not perfect, but no system is. Anyone can justify their actions by blaming the flaws of the system. That is never a valid excuse.
Point out the flaws by all means. Come up with valid alternatives. But don't abuse those flaws to artificially improve your statistics. You are better than that.
Congratulations on winning 100 games together. Well done on breaking the win streak record, and I hope you learn from your mistakes and set a better example to newer teams.
