What happened to the Warden class?

Remember how back in previous seasons there were always 2 types of tank supports. Those who engage and those who peel with cc. Now the only tank supports are engage and it’s very annoying because as a support you either pick fragile peel mages that get one shot or pick tanks who are expected to be the front line because once you go in, you can’t really just walk backwards to peel for your adc because your won’t adapt to you suddenly leaving the frontline to peel.

Why is it that all the wardens either got gutted or lost their peel abilities. Tahm got moved to top, Braum is useless right now because he uses so much mana and can’t tank anything, Gallo got gutted. The only ones left are Shen and Poppy but they don’t even go support. It’s stupid that the only ones that can act as Wardens are not even supports.

Why is it that Shen and Poppy can peel better than the tank supports designed to actually peel. All we have is Taric and as much as I like him I get sick of choosing him every game just so I can peel while avoiding being one shot.
