please remove the global dragon/baron timer/message. This is a skilled game where Fog of War and understanding buff timers is entirely imperative to the gameplay. Take a step back and look at the game you're beginning to ruin.
If nobody sees the buff being taken, the icon stays on the minimap. This is EXTREMELY DETRIMENTAL to catching enemy players as they try to make plays around the buffs that may or may not be there.
the idea of leaving a fog of war effect to EVERYTHING UNSEEN on the map is extremely important in determining where to go and what to do. It is a battlefield that we play in, not a timed global indicator.
