While I can see it helping out in low rated games, it will ruin some of the more complex play in higher brackets due to killing off some of the strategies that thrive on abusing other players early or doing unconventional plays.
Imo totally not worth the time for higher bracket games, or any games in competitive scenario as it makes it impossible to properly abuse other players in early game as recovering from first bomber will be much easier.
As for casts? Skill issue kappa. Instead of looking at the BO caster should try to speak about the map and players. What type of gameplay the map is promoting and what can we expect the players to do? What kind of cheeky plays are possible etc. So it's not fault of BO's being boring but rather FAF casters (me included) being just bad.
