No tank main wants to be immortal
You see all we want is to be invalid targets
basically it would take too long to kill us and using your damage on us is a waste of time and effort
In return we are shite at killing other champions, but good at disrupting their efforts or having other ways to draw aggro so people are forced to play around us
The problem lies in tank design and the tank update did literally nothing to address it
If we want to be that though we need to lose damage, specifically spammy aoe damage, yet we still need it to function because we still need to farm
The other problem is that tanks aren't inherently more tanky then other classes, you cannot make defensive items so powerfull that we would achieve this fantasy or they will be abused to hell and back
So if we ever want this to be a thing then we need to give tanks tools to farm
And tools to make us threatening in a fight
Sion is halfway there, he lacks the farm tool as most of his damage vs minions/monsters is restricted. he can deal ok damage to enemies though and has the cc to force them to play around him
You can outplay that
Doesn't mean every tank needs to be like that though there is more ways to make a tank disruptive etc
If we want tanks to be stronger vs damage then we need to give them tools to farm so we can get rid of the spammy aoe which lacks counterplay and make their damage and threat outplayable to a degree then they can be more tanky
But this bulk has to come from their kit in part and synergize with tank itemization rather then just through tank itemization
This means we need to overhaul every single tank in the game
