the problem with tanks
The biggest problem with tanks in league is that none of them actually offer tanking abilities (except braum). Which makes them a nightmare to balance. it's either that they're too weak, or that they deal fuckton of damage with no counterplay since u can't fkn move.
By having every single tank have 3 hard cc spells in thier kit you limit thier power since if they get a little stronger they'll make everything that isn't a tank suffer. All while not doing what tanks are supposed to do: tank damage. take a look at games that have succefull tanks(overwatch for example), you'll see that tanks do infact have abilities that makes them tank damage from thier team and not just hoping that the enemy team focuses them or cockblocking the entire team with cc, giving 0 counterplay
