First,how can you know that kakashi's PS is weaponless ,whatever what is madara's answer for long range kamui and intangibility?EMS? Since when did obito or kakashi have siblings?
Anyways, kakashi still gets stomped. Does his temporary PS even have weapons? Or is it restricted to taijutsu..
I think people are in denial ,they hate to admit that current kakashi clearly beats ems madara,they don't even explain how ems madara (with or without kiuybi)will counter the intangibility and long range kamui while kakashi can deal with all madara and kiuybi attacks
