I do not believe you will actually be able to notice the difference/changes from the adjustments in point differentials yet from wins/losses until you reach gold. +25 for wins and -15 for losses sounds exactly the same as what we had last season in bronze and silver tiers. It wasn't until Gold that they started slapping you with the unfavorable weighted losses when compared to wins (stuff like +19 for wins and -29 for losses). Generally speaking, during bronze and silver tiers wins always netted you more points than losses subtracted from your rank after they made adjustments to it following the preseason which had like 95% of the player base stuck at bronze and silver.
