Summoner spell cooldown

Why not add summoner spell timer UI support to this game? Riot already added jungle camp timers. As it stands you get into a fight with enemies, after the fight you ping the summoners used via the scoreboard and it pops up in chat along with the current time. Why not add functionality to display summoner spell cool downs in the scoreboard interface. In top level league, challenger players already do this mentally, but players who are not as dedicated aren't encouraged enough to time EVERY single summoner mentally. Adding this feature would make top level play more accessible and overall improve quality of the game without taking away skill just lowering the already high barrier of commitment required to be a master of league of legends. Thoughts? Counter points?

PS I don't mean it should automatically show the SS CD for every enemy SS used, just add functionality to allow users to click to keep track of the timing without forgetting or having to do math. Obviously there are also CD modifiers that would have to be factored in. PS inhib timers would be helpful as well and improve the quality of game play in league of legends [vayne-pose]
