Look at the title: '''''The World''' Is Yours''!
Having Dio's time powers would explain all the stuff that he gets to use in Blind Rage. Invincibility is the result of time-locking his physical condition so that none of the damage Tony takes will be fatal. Healing through wounding enemies is extended from Dio's vampirism. The time-locking also explains why reloading a weapon while entering Blind Rage leaves you unable to fire, as opposed to "refreshing" your ammunition count every time it runs low (like in ''VideoGame/CliveBarkersJericho''): the ammunition status is time-locked at whatever it was at upon entering Blind Rage.
The reason why Tony needs to build his Balls meter is because he does not have mastery over it yet, but give him time.
As for why it does not stop [[Main/IncrediblyLamePun The World]] around him, maybe Tony prefers to give his enemies the illusion of having a chance. It fits his personality.

That's why he can take so much abuse. But TOO much abuse can overwhelm the healing potential.

[[WMG: Tony killed his mother by the start of ''The World is Yours''.]]
In the start of ''The World is Yours'', doesn't that house Tony went look familiar? If so, that's where his mother, [[IHaveNoSon who disowns him]], lives. Later in the story, she is killed by the Diaz brothers. An alternate interpretation, however, could be that after losing his empire by the hands of Sosa, Tony ended up trying to find a place for refuge and the only refuge he could find is his family home. But his mother won't allow him to stay; this finally send Tony into a rage. Finally had enough of her [[WellDoneSonGuy not approving of everything he does is to help her]], he [[AssholeVictim killed her]], and being horrified by this, blocked out the memory. As a result of his stay three months ago, he ended up forgetting he committed that crime.
