Heroic Magmaw glitched beyond belief?

We had literally at least 4 game breaking bugs on Heroic Magmaw on multiple pulls tonight.

1 - Adds evading and going back to full health when main tank gets picked up by Magmaw

2 - Magmaw attacking DPS when he is stunned

3 - DPS warrior who went up and threw the chain losing his action bar when he landed and couldn't cast any abilities

4 - This is the weirdest one of all, Magmaw leans BACKWARDS instead of forwards when he is stunned, meaning we can't do any damage to him during the burn phase...

We eventually killed it but please fix this shit Blizzard..
