The norm for competitive games had become team coaches being able to talk to players only during half time or during tactical pauses. This was the result of a valve ruling disallowing coaches to practically act as the sixth player in game.
On EPICENTER tournament I am allowed to talk to players on teamspeak any time. That's why you see less pauses than on ESL One. pic.twitter.com/UTUS7ddqSb
