Hello. If we would have this system implemented, then we would have to redesign monster displacement, timing, difficulty, and the claiming feature.

Displacement: Reorganize monsters into a much more traverse pact in a multiple amount of area's so multiple groups can party effectively.

Timing: Respawn rates would need to be organized into longer delays so people don't just get +1000 chain.

Difficulty: This is not in level gap. Much more ferocious attack damage so it'll be legitimate for role displacement like Gladiator to tank.

Claiming feature: Would have to do away with the current feature and allow us to claim another target while the first is near death to allow the chain to progress rather than wither and die.

When someone said that all you would see is 5-6 mages pulling everything and nuking? No. Pulling multiple monsters would net you the same result as it did in XI. Death. Too much damage sustained.
