2 days ago, in the FURIA vs NRG match on Dust 2, molodoy's trigger discipline attempt was ruined when yekindar team-flashed him. As this info is not shown in the in-game kill-feed, the casters didn't realize it was a team flash until the round after, and someone had to go rewatch the round and confirmed to the casters (timestamp). Similar confusing situations have occurred plenty of times in the past (note: that imgur link contains the clips for the scenarios in the above table). These examples highlight the limitation of current kill-feed, so I think it should be improved further. This suggestion is not (just) for the TOs, but for Valve to add it natively in-game for everyone. For those interested, here are other relevant posts on the topic (post, post, post, post).
