24. Why is it so difficult to upgrade ultimate abilities? Why can't all heroes upgrade them? Why aren't they equivalent to each other?
In short, ultimate abilities are bonus abilities, a pleasant but not essential reward that can be obtained towards the end of the game as a reward for extra effort – that's how they should be perceived, and that's why they are so difficult to obtain, and that's why the game doesn't show anywhere the path leading to their acquisition. Getting these abilities is like hitting 10 targets out of 10 in a shooting range.
