"We're nerfing mana mages because they have cc and act as a secondary support"
Meanwhile, looks at:
Stuns/Suppresses: 
Knockups/Knockbacks: 
Roots: 
Didn't include slows since they don't immobilize people and pretty much every champion, aside from champions that have other forms of cs, already have some form of soft cc (BORK, Frozen Mallet, Rylai's included). I only included the roots because I have my reasons.
Not only that but nearly half of these go Predator, how do you even run away from a 
with 800 movement speed with just 
and the rest tanky items. Some mages can go tanky (
), but on others it's pointless to go tanky (
) plus most don't have mobility and can be towerdived, and the rest is just season 8 blah blah blah. AD champs are just better since there's no late game anymore, you might as well just remove damage from mages and give them all heals.
