In the current meta and proved yesterday by Immortals vs Renegade, who needs tankyness and cc when you can just kite/burst any engager before they can do anything.
Whenever I see my 4khp 300armor 200mr full tank just get decimated in the time it used to take to nuke an adc last season, sometimes I wonder why I even play any non-support tanks anymore. Why should I bee pidgeonholed into playing Malph or Nautilus if I want to tank? Malph is only viable because of his assassination pattern and Nautilus because he has overbearing quantites of CC and a shield that makes him even tankier than most tanks. What about other tanks, the ones that can't assinate or lock down your entire team? Don't they also deserve to be viable?
