Thats why when i lost in seasonal ladder to mod I instantly leave seasonal ladder. He dont respect other players wins against him, i dont respect him :(
Fun fact - it doesn't hurt him (much)- with only few games in seasonal your overall rating is very low as you don't get bonus points for every finished games. But it does not influence other people ratings, cause your "real elo rating" is quite high (at least it shouldn't be low with 7-2 score) and it's all that matter. (In other words - if you want to screw someone result don't leave, just stay and keep losing:D)
