I've pointed out before that Susanoo is superior to Ashura path, so there's little reason for madara to use every single technique.

Secondly, it's not at all clear that Madara was able to use his EMS techniques.

Thirdly, Madara was messing about with the Five Kage, with Hashirama, Guy. it wasn't until Naruto and Sasuke's Six paths power that he got serious and quickly obtained his Rinnegan, then immediately cast Chibaku Tensei as a diversion while he cast IT.

Lastly, we know that limits to the Rinnegan exist (IE Sasuke can only use 3x Ameno before closing it). Madara hid his weaknesses well, but notice for instance that after he sends out his Limbo clone, he apparently couldn't absorb the Lava Rasenshuriken.
