It is a bit odd that there are these two forms of currency for character advancement. There's also the problem that players who spend their Hero Points doing heroic things are hurting their chances of buying heroic abilities.
So, should Heroic Abilities be purchased with Hero Points? What should the exchange rate be?
Maybe the second problem could be addressed by having a "spent" pool of HPs that are used to buy Heroic Abilities. This would encourage players to spend them. In order not to speed up the acquisition of Heroic Abilities, maybe only Hero Points that are spent unsuccessfully should go into the pool, as a kind of consolation prize.
