If you watch the live match, you know when playstyle is in effect. It works just like the speciality, small icon shows up on the player with his playstyle. I feel the frequency of playstyle coming in effect is more often than speciality though. Playstyle have 3 levels, standard, intermediate, and master. I believe it will make quite an influence in the game once a player reaches master level.

My concern is if playstyle can influence the counter formations as we know. I'm guessing it does, especially with master level. But then any high quality player could play beyond counter formation trap.
