So personally, I find Global Averages to be the only really interesting numbers in the post-game screens; masteries and awards are just stuff you accumulate over time, and don’t really show if you’re improving or not as a player. With averages though, you can know how much better (or worse) you’re doing with any given tool.
The glaring problem of course is that how much damage you do or how much you heal or shield varies HUGELY depending on how long the match goes; this renders the current average system as more or less meaningless.
HOWEVER, this could be completely fixed if the game simply separated averages by how long a match went. To make it easy you could simply divide up each average by minute; aka, if your match lasted 11 minutes, the post-game screen would say “Global averages for an 11 Match:” then show you the three numbers.
I’m guessing this would take more work than it’s worth for TRS, but it would be very cool and would be hugely helpful, as there really isn’t any way to tell how well you’re playing a given class (Masteries are just a grind and take no skill, leaderboards are just based on how long you’ve played, take no skill)
