I think a lot of people here are familiar with the raid save transfer thing.
Basically, you clear a raid, say ICC, 11/12 on normal 25. Then you go outside and invite your alt, alt goes inside, accepts the 11/12 normal save, then changes it to 25hc while inside to get a unique save ID. You can then kill LK on more than one character even though you only cleared ICC once.
It's explained in more detail here, and it says it works for Lich King raids and up.

There's even people in the thread saying that they do this to get easy Ragnaros kills.
And that's where I get confused, because for this method to work, you need to clear the raid on normal, then change it to heroic for every individual character. Problem is, you can't kill Ragnaros on heroic if you clear the rest of the raid on normal. I've tried that in the past and know for a fact it doesn't work. I even ticketed a GM back then and he told me that to kill heroic Ragnaros, you need to kill all other bosses on heroic.
Can anyone shed some light on this?
