Immortal ULT Spammer Tank Experience [Updated]

This build works best against a team with a couple of enemies with fast shooting projectiles (such as Soldier and Reaper, you can farm your ult by deflecting their ults). Not good against heroes with beam based weapons (like Mei, Zarya, Moira). Keep in mind that Orisa's weapon is heat based so ammo increase items are useless, also faster shooting items will cause your weapon to overheat quicker.
