For the love of God, please address Conqeuror healing

The problem with conqueror is the massive discrepancy in performance for champions; the fact that the are multiple champions that can almost immediately fully stack conqueror and then get so much adaptive damage and bonus healing is absurd. There are too many champions that easily abuse this and basically sit there face-tanking it with the a near Blade of the Ruined King in base stats. No other keystone performs at this level when fully optimized. It needs to be addressed and drastically toned down. It would be one thing if the Keystone didn't activate until fully stack, but each stack of conqueror grants adaptive damage. Even when not fully stacked it still has value. At the very least the healing needs to be toned down.
