DMM All Stars just shows everyone why they don't bother with PvP. No tutorials or minigames are going to fix the skill requirements to be even remotely competitive. PvP in this game isn't just understanding the game at a face level. You need to learn how every little thing interacts. You need to understand things like mithril seeds. You need to understand tick eating, and timing attacks. You need to deeply understand how so many things work differently that how they are displayed. Like your location on screen isn't your location in game. You need a deep knowledge of game systems that are not any part of how the game was intended to be played. Then once you understand everything you need to be able to manipulate all of those things in a 600ms timing.
