Okey here's when we all realize you are a hardcore fanboy.
1- Bunshin feints aren't workind? Based on what? Kakashi's bunshin feints are one of the best of the manga, having outsmarted Pein and Itachi between others. The gap between minato's base speed and kakashi's bases speed became a lot smaller during the war arc. You saying Kakashi's feints aren't working is totally biased, bunshins are the key for kakashi winning this match. I'll give you the genjutsu thing tough.
2- Kakashi's raikiri has two variants that can't be countered with rasengan, lightining chain (that covers a pretty big area) and lightining running beast. Kakashi using those atacks combined with clones as distractions can give him the victory, since using those techniques he could blitz 4 v2 jins, so why not minato? Without FTG his speed is not that far from Kakashi's, and he doesn't have great defence techniques to block kakashi's atacks.
3- Minato's striking speed is really fast due to FTG, show me a panel of his striking speed without FTG. Minato's base striking speed is fast but not one another level, Kakashi can keep up with him. And Kakashi's taijutsu feats > Minato's. Also, Kakashi has great reflexes feats too, he reacted to susano arrows that are really fast. Lol at "taijutsu suicide" for kakashi, since Minato without FTG has no taijutsu prowess at all, and Kakashi has one of the best taijutsu techniques of the manga.
4- Oh lol, now minato has v2 Ay's striking level speed with just sunshin? Minato needed FTG to keep up with Ay's speed, don't make me laugh. Minato's sunshin is not even close to v2 Ay's sunshin. Minato is not speed blitzing kakashi without FTG
