For anyone that kept saying...

That Vegeta should've went Super Saiyan 3 against Beerus cause he was enraged and because he didn't, that means Daima is not canon to Super.

Let me ask you this, why didn't Vegeta went Super Saiyan Grade 2-3 against Cell when he killed Future Trunks? He was so much enraged here cause his son just got killed, doesn't matter if he knew the flaw of those forms, he should still went to it cause he was in rage.

Both Super Saiyan 3 and Super Saiyan Grade 2-3 have exceptionally high ki reserved but incredible draining stamina...
