they leaked communications from Kru for about two rounds or so and I understand that it's an off-season tournament, but they may have still leaked some strategy or calls from the IGL
This type of "listen in to the comms" is very common on the off-season. It gives viewers a deeper insight into how pro-play works and what is being said in the moment. Adds to entertainment and analysis. Also, it's an off-season so nothing big should be revealed. It's still semi-serious as every pro team would wanna win prize money or get some extra clout/support. Teams have plenty of strats and adaptations usually.
