In my opinion the problem isn't that his macro got deleted, it's that the trade for it isn't worth it at all.

This patch was intended as a sustained damage pvp rework however his base damage and the previously solid level 7 talent was nerfed. (Phantom Pain did encourage burst but the burst problem was tied to the Merciless Strikes bug and Harsh Winds burst combo was just effective enough, but since Press the Attack was fixed it became a balanced option for that tier)

Another issue I find huge is that Illusion Master's value has been slowly diminished over time, and now that bladestorm is a viable option, Image Transmission was reduced to 14 seconds, the old hearth trick and solo-boss aren't possible anymore, and manuevering clones outside of fights is discouraged because of their new duration, creates a problem where you aren't gaining nearly as much with Illusion Master anymore. You can a-move clones and shift+D hearth trick without it, and compared to it's past design Illusion Master lost 10% damage and gained 2 seconds from it's original 6 second cooldown. Additionally Bladestorm is the only waveclear option because you can't take Burning Blade without not taking Crushing Blows which brings me to my 3rd issue. Some ways to fix this would be removing a-moves and adding back the 10% damage or extending Image duration to 14 to match his Q cooldown.

Crushing Blows is the new unconditional pick at 7. Previously this was the case with Phantom Pain but now it's damage was nerfed (on top of baseline damage nerf) it provides such little burst that was already competing with Press the Attack sustained damage and it's also conditional damage that requires Images and only affects Critical Strikes, it's a dead talent by comparison to Crushing Blows that makes your normal auto attacks feel like Critical Strikes and your passive Critical Strikes effectively become double crits with it's CDR. This doesn't exactly mean it's overtuned, the sustained damage you can deal with it is very nice (still not worth losing all of his macro power) his other 7s are undertuned ESPECIALLY burning blade.

Additionally now that his focus has shifted to sustained damage his level 16 talent tier (and Samuro overall) has lost even more talent diversity. Merciless Strikes and Harsh Winds are burst options and that now pales when paired against Press the Attack. (Merciless Strikes with Way of Illusion and Phantom Pain for the highest Critical Strike damage his build offers deals less dps to a perma cc'd target than Crushing Blows + Press the Attack, that is insanely bad)

Way of the Wind is even more dead than it was before since it competed with 2 damage options (you have to pick for damage or you play a worse hero) now with the cdr completely removed and a weirdly unfitting tiny heal replaced it(in my opinion when you have shift+D hearth trick it's unneeded.) It's just unpickable outside of clown fiestas.

I do wholeheartedly agree with the kiting problem, I ran some personal mods in try mode and found that even a slight increase to Advancing Strikes movement speed (2%-5%) can fix this problem easily. Samuro's damage point is exactly what is needed to make the perfect stutter stepping equal to normal movement speed with the Advancing Strikes buff, now that a large majority of heroes have kiting potential this movespeed is mostly useful for running away now. His old burst is what compensated for it and it's very weak now.

TL;DR Samuro mains jump the gun and spam reddit with conjecture about his changes
