Unfortunately what a "true tank" is is based on each persons opinion, for example I consider Shyvana a tank because her damage output makes her a target that you want to eliminate, allowing her to soak damage like it is a tank's job to do. Her ult also has the "Oh crap, giant fire breathing lizard, kill it quickly" effect.

CC is not the main thing that makes a tank, though it does help, sometimes being beefy and dealing a good bit of damage while inside the enemy team makes them want to focus you allowing your team to stay as safe as possible.
