I like how snide you are towards those who apply actual manga feats, rather than imaginary ones. It's actually illogical to say Ace has it. The word you're looking for is Reasonably, Ace has it.
Calm down guy, every time someone mentions your name it's not snide, I know your used to drawing that reaction out of people so it's understandable why you'd expect it so often. I said ask Riker because you reference those instances so much against me in other debates I know you're more familiar with them to explain it to him. He asked what imaginary damage, and I don't remember the fight with Smoker so clearly and didn't have time to go re-read the chapters looking for it.
And for the record, you're using instances shown in the manga as a "reason" Ace doesn't have it, but following the manga's presented logic(Shichibukai should have it as a force comparable to VA's and he was asked to be a Shichibukai, was being groomed by WSM to be PK, was superior to Luffy in every showing and was passed the age Luffy was when he learned, He fought against Jinbe for 5 days how would someone made of fire manage that exactly if they could only dodge yet we saw he had damage?) Ace should have it. So logically, based on the precedents in the manga, Ace should have had a showing of Arm. Haki. It's reasonable to say he didn't because there's no case demonstrating it. But I'm not gonna argue with you over semantics and which words you choose to use.
