Unless I'm mistaken, I have max mana fury, and it crits at 2.25 the base rate of the spell I'm casting. This is easiest to see with either no focus, or with using panther (which hits for full or not at all). Panther is normally 400, and I crit for 900.
However, Samanna's tables:

suggest that Destructive Fury is 25% bigger crits, and Mana Fury should be more.
Now, I seem to vaguely recall wizards saying something about one AA being nerfed so that you need to buy new AAs to get up to the level that you previously were at. Has the same thing happened here? The wizard lines are different to ours, even though some of them have the same name, so I can't go on wizard %ages to check. I didn't have any nuke AA back then, so it didn't affect me at the time at all, I've really only bothered with it seriously since we got Sting.
Can anyone confirm actual percentages now of Destructive Fury and Mana Fury at levels other than MF3?
