So, if for example, the top 5 teams in 4v4 for both factions showed a similar set of results or 'balance', yet the bottom 6000 players showed a swing of 30% or more to a particular faction, that would be fine with you?
Is that what you're saying?
That was directed at Acolyte, but yes snip.
You aren't comparing apples to apples then. The bottom percentile in team games is void because almost all of those team can break the top 200 just by playing 10 games. This is why you use a scale effect in team games to counter smaller AT populations.
"Why the bottom percentile shows a larger swing"
Paidplayer aka Legends just said this was due to popularity over balance. I think hes spot on.
The argument for random teams vs AT is pretty straight forward. If the top 4 players in the game played mirror matches of themselves in a vacuum, this would yield the most accurate result of balance. Obviously this impossible so we use the next best available data, AT.
