So, on level 20 Li Li's heroic ability "Jug of 1,000 Cups":
Rapidly tosses brew to the most injured nearby allies, prioritizing Heroes, restoring a total of 3600 Health over 6 seconds.
... and can be upgraded to "Jug of 1,000,000 Cups":
Jug of 1,000 Cups now hits two targets at a time.
I can interpret this as one of:
a total amount of hp Li Li can restore now equals to 7200 (assuming there are 2 or more heroes being healed)
a total amount of hp being restored is still 3600, but now it can heal up to 2 times faster, i.e. 3 seconds (assuming there are 2 or more heroes being healed)
Which one is really happening here?
