I'm really sceptical about most of the stuff, tbh.
All that armor-imunity stuff feels like fixing things that shouldn't be broken per se.
Slightly exaggerated example:
Ofc CC is too important, if I need a hundred hits to kill something, because it is absolute and instant instead of the damage's consequence (death). Right now, a proper mage can be killed within a single round by one enemy easily, sometimes one single hit. (for example deathknights) And ofc the player needs to utilize CC to prevent that to be successful, making it way to attractive.
Balancing these aspects would be the better way to tackle this, imho.
