Yeah I don't think so Luffy was literally in base and zoro wasn't serious. The moment zoro started emiting haki and Luffy went gear 5 Gaban simply realized the hero they were waiting for has arrived and stopped testing them and left. Right now what Mr love have against Luffy is adv adv conc haki. But we don't know how overpowered is it yet other than it can kill immortals
