Mages Dominate Mid Lane Because Assassins Are Awful Right Now
It's pretty simple. The thought that the entire Mage class warrants a nerf because they have been dominating Middle Lane in pro play for a while is pretty clearly because Assassins are just unreliable in pro play. When you give people a warning indicator/delay on every Assassin, it basically turns dealing with every Assassin into a boss fight that has a pre-made script you have to follow. Believe it or not, pros are really good at following this script. Assassins need to not have innate, no work around delays in their kit, and INSTEAD people just need to ward more and/or we need to have innate objectives in the map that allow people to be able to work around Assassins without just making Assassins into a scripted encounter.
