"Enraged Assault changed to "You regenerate 30% of your total health over 10 sec. This ability consumes all Enrage effects and prevents any from affecting you for the full duration." (Old - A furious assault that consumes an Enrage effect on the warrior and attacks with all weapons. Can only be used while Enraged.)"
Says nothing about being removed, just changed.
*EDIT* - And even if it would've been removed, wouldn't you've liked to see some kind of update/correction of the talent?
The information in the front page is slightly false - Enraged Regeneration wasn't "updated", it was removed and replaced by Enraged Regeneration (I think that's how it's called).
And the reason that talent wasn't changed is because either they want to replace it completely but it wouldn't have made it to this build so they decided to leave it as it is because it's irrelevant if it doesn't make any sense now because it will be replaced anyway, or they simply forgot to update the talent.
