The issue with that kind of item is that tanks need to deal just enough damage that they're a threat if ignored.
Otherwise they'll QSS or disengage and you're now an easy source of health for marksman.
Tank items in general need a buff. Made a post ages ago, but tanks have lost exactly 850 HP and 55 armor over the years in their items.
Tanks need their own super items worth 3K+gold (like old warmogs) that grant stats to match.
IMO (note this is a straight cntrl C+V from old post, so some from X may be incorrect)

Perhaps ur item idea could function like "courage of the collosus" When a tank uses hard CC, they gain a shield for X second based on their bonus HP (to prevent juggernaut abuse)
