The efficiency mod really shows the average skill of players.
*k = amount of battles rounded to the nearest thousand (0k = less than 500 battles)
After that comes efficiency according to this chart (a pretty accurate indicator of skill)
And lastly the win ratio which is p useless
I feel like playing amidst a bunch of monkeys. Enemy l÷wes too, one has 200 fucking efficiency, how can someone be that useless every match. And note how few battles both enemy l÷wes have, bought themselves from low tiers to high and it shows.
Edit: The enemy KV with 177 efficiency was the first one to die.
