I have an aesthetic issue with the token system (Iron Heroes). I'm concerned that by the time you accumulate enough tokens to do your Cool Thing the combat is over. If the combat is not over, the situation that warranted the Cool Thing no longer applies - potential target is dead, moved out of range, no longer as much a threat because party member did something, etc.

I don't object to a resource management system to do Cool Thing effects; it's just the token system way I don't like. I like the Expertise Dice system because you can decide to do your Cool Thing right then and there and be able to do it. You spend enough Expertise Dice to do it. Big Cool Things require more dice which you get when you level for when those Big Cool Things are more appropriate. The token system encourages use it or lose it mentality; you risk never using it if you need to accumulate a lot of tokens over rounds of play to do a Big Cool Thing.
