For my M2Air, I downloaded the external version of League of Legends (lol) from the Kingpin platform with a try attitude. Then I played the game on the PC version. I used the recently launched Thunder God Accelerator for Mac on the external docking station, connected it via an Ethernet cable, and it was really comfortable to play the PC version of the game.
The highest quality setting maintained a stable 80 frames per second without any lag.
The lowest quality setting could maintain a stable 100 frames for the Battle Royale mode, which was very comfortable. Come and give it a try right now!
