Personally, I think the cams have value for spectators who aren't sitting on top of the client at their PC, I pay way less attention to the minimap when I stream on my TV than when I'm sitting at my PC. Also for casuals that don't know about the rest of the information or have the skill to decipher the minimap mid game (which is plenty of the spectating audience) some of the information is value. I certainly agree that some of the uses were not as smooth or as relevant many of the times they'd show things, but I think you could say the same thing about a lot of the spectating tools. Innovation in how information is displayed for spectators is good, just like the yellow first down line/other shit sometimes projected onto football fields. Not everything lasts, like that puck with a trail technology they tried in hockey in the 90's. They gotta try shit to figure how it works, and to work it better in live games.
