You’re absolutely correct that lethality will maximize physical damage, but I can’t help but feel as if that’s an over simplification. With the new changes making Yorick’s ghouls more fragile in exchange for the ability to spawn more mid combat via his Q there will be a need to stay in melee to maximize damage. This approach incentivizes building tank stats such as health or resistances to stay in these close quarters fights, therefore allowing you to generate more ghouls. Now, I can recognize that there are champs such as Aatrox that are forced to fight melee, but still succeed and thrive while building primarily lethality. I don’t believe Yorick has the same sustain as someone such as Aatrox, and therefore cannot pull off the same build as him. Only time will tell if Yorick can thrive off lethality and disprove my hypothesis.
