STOP DOING THIS TO TANKS!
the single reason that tank meta is even more toxic than the current meta is due to the high damage tanks had.
tank are supposed to TANK damage, i have no problem in taking 15+ secs in killing somone unless this one kills me in 5 seconds. the things you're doing to sejuani and ornn are the opposite of what tanks are supposed to be, you're turning tanks to fighters and that's not cool.
tanks are supposed to have alot of cc, yet you're reducing the cc in favor of more damage, that's not how tanks are supposed to be. if you want a meta where the team with the most damage wins, it's fine. but be clear about it. don't buff tank's damage AND survivability while reducing cc.
in my opinion, the ideal tank is someone with enough cc to be presived as a threat, while being very hard to kill. AND AT THE SAME TIME not having such a high kill pressure. a champion with high survivability and high damage is a balance nightmare.
