Why have the Minimap Icons changed to be so s m o l ?

The Minimap even on 100% has always been kinda small and the Icons on it, but atleast you could notice certain things.

Now you can hardly see the difference between a broken Inhibitor and an UP Inhibitor or a Drake/Baron that is available to make a call.

I don't want to spend 20 crucial seconds more looking at the Minimap wondering if that Tower is already taken or not.
