The problem isnt 'too much damage'

The problem is 'a lack of a viable tank in game fantasy'

Tank items are boring and characterized by noon interactive passive and auras.

Tank champs suffer the most from 'only the best in category can be played'

Dmg items feel more interactive and exciting particularly for the buyer of them.

But 3 class updates in a row focus on making damage dealers happier.

Yes juggernauts aren't tanks. And their items are boring and less thought out than the mage and adc received.
