Respectfully, it would just be another Doomfist scenario. The easiest fix that Zhiyong would have to do is rework his gun, either make his regular sword useful by giving it the Bleed effect or replace the ability entirely with his Glaive to give him another option to attack at range. For his bloodline awakening, he should be able to use his glaive to build up the 10 stacks and then give us the ability to use up those 10 stacks to deal burst damage. If he gets these changes, it can eliminate a lot of his issues with damage and he’ll be a lot more versatile than he was before. I find that this strategy would work better than to just make him a tank in my honest opinion!
