Bladed Capes and Tormented Icefists
So Blade of the Ruined King and Liandry's Torment were items, still are, designed to help deal with tanks and bruisers whenever they get a little out of hand. And then there is Sunfire Cape and Iceborne Gauntlets which may be dealing a little too much damage for being tank items. So you have the items that are meant to deal with tanks getting nerfed a bit with these damage tank items getting buffed quite a bit; and these tanks items are brought up because when almost anyone can build these two items and still not a significant amount of damage for it then there must be something wrong here.
Sunfire Cape: None numerical balancing would be lower the damage to champions and then increase the damage to minions to emphasize its role to help tanks clear waves and tone back a tank and bruiser damage against squishies.
Example: 20-38 magic damage per second from 25-43; minions takes 100% increased damage from 50%.
Iceborne Gauntlet: None numerical balancing would be tone back the damage the sheen effect does making the item more about its defense and utility than a damage output. If this would need a follow up buff to something else on it then it can be assessed in a patch or two in the future.
Example: 100% base AD down from 125% base AD [Sheen is 100% base AD].
Blade of the Ruined King: None numerical balancing would be increase the passive damage slightly just to help the item deal with tanks better and the passive is mainly only good for marksmen which are meant to kill tanks.
Example: 7% current health on-hit from 6% current health on-hit as physical damage.
Liandry's Torment: None numerical balancing, and this one is under the premise that Will of the Ancients is being removed, add a new passive that makes the damage from Liandry's Torment heal you allowing mages to survive against the brutal onslaught of tanks and bruisers without having a Vladimir only item since the damage is a burn that plays around cooldowns on mages better (also makes the item a little like Blade of the Ruined King since it has life steal). This mechanic also restricts healing from minions since the heal would be a % health burn against low health targets.
Example: 50% of the damage dealt from this item heals you [based on what the item deals people, not all the champion's damage].
