so what was the point of removing "oppressor" mastery?
Champions either have crowd control abilities or they don’t, making Oppressor a pretty ‘yes or no’ mastery. How you play your champion makes little difference when the only question is whether you can do something or not, so we’re removing Oppressor in favor of something more flexible.
lets add "courage of the colossus" and remove "strength of ages" this will fix everything...
Courage of the Colossus
Giving initiators a survivability tool in the moment they need it most: diving into the enemy team.
Gain a shield for 7% (+7% for each nearby enemy champion) of your maximum health for 4 seconds after hitting an enemy champion with hard crowd control (30 second cooldown)
. But if you're more 1v1 oriented you get Grasp, or for small skirmishes you get Bond. It's a question of how you play the game.
