France vs. Ukraine
Sweden vs. Russia
TBD vs. TBD
I don't have firm data to support this, completely anecdotal.
However, pre tower/minion changes, I feel like I would never have a match that would result in less than 100k XP. Now in wins it feels like my matches result in 100-150k XP, and my losses are 50-80k XP.
It may be a byproduct of the matches lasting way shorter amounts of time, however I feel like this winter veil it's just not even worth trying to level heroes for boxes. Then again I don't remember a single game prior to the tower changes that resulted in less than 100k XP.
Once again purely anecdotal. Would love to see data if anyone actually tracks that.
