Congratulations on the trophy!
The problem is the point system and not a player. He is not the first who stalls a bit and won't be the last. Everyone who does ladder runs, does trick the ladder system. If you want to be a deserved number 1, you need to keep it for a longer time period in games against good opponents. That is my point of view.
Would have done the same myself, I imagine....sadly I can only imagine *sob sob* gib me worthless golden trophy plz.
