Or maybe you just got lucky after a few early mistakes and quickly gained an overwhelming statistical advantage over them, with no way to recover. They were, after all, matched in the same game as you. They should all be at around the same skill level as you. Ever heard of the Dunning-Kruger effect?
This change does nothing to increase individual impact in games, because if your teammates screw up in the early game and lose out on EXP, it’s all downhill from there, and skilled play will only get you so far when the enemy team has a 2-level lead.
I’ll just leave this here, a very relevant post by the devs made in March of 2019:
The devs spent years fine-tuning EXP gains so that the losing team would always have a good shot at making a comeback. Then they threw all of that out the window with this ill-conceived mechanic.
Before this change, it was quite rare for the losing team to be down a talent tier for more than a minute. Now, the winning team often has a 3-level lead by the end of the game, and the losing team spends a large portion of the match down a talent tier because they can’t safely farm EXP.
