Urgot Rework Archetype Idea- Damage Drain Tank

Currently, Urgot is, without a doubt, in a sad state. He by all means is bad. However, he has these two things that separate him from the rest of the game:

1. % Damage Reduction Debuff His Passive is a really boring, yet unique little thing that allows Urgot to reduce the damage a target deals by 15% for 2.5 seconds. It's really boring, yet the most unique thing in his kit.
2. % Damage Reduction Buff I know this is on some other characters, but Urgot is one of the few characters to have huge % damage reduction in his kit. It's on his ultimate, for those that didn't know. It's a huge 30-50% global damage reduction after use.

So, my idea for an Urgot rework is to make him into a Damage Drain Tank? What do I mean? I mean that he leeches damage from his enemy. Urgot is this cyborg, undead abomination that is in constant misery. My idea is that he wants to drain the power from his enemies to lessen the pain in more than one way. Make his Passive something that maybe makes his target deal % less damage and him deal % more damage. Maybe give him a heal as well instead of a shield to further the identity of him sucking the power from his enemies. Instead of trying to push Urgot into an Artillery Marksman direction, which is kind of a boring direction really, we should push him more towards his Durable side. Make him a super aggressive Tank that steals his opponents damage. The first Tank that might require focusing since you're potential for killing is reduced as long as he is alive. A Tank that actually FORCES the enemy to focus them without a Taunt.
