I have a whimsical idea for a weekend project.
I would like as many people as possible to look through the hero abilities of published heroes and rate them for how powerful they are, overall, on a scale of 1-5 (5 being strongest). Please rate just the ability itself, without taking into account any of the other stats of the hero who has it--for example, Eliam's stats seem to be designed to weaken his ability (which is fatigue-intensive on a 3-fatigue hero and doesn't work with his strongest attack type), but the ability itself is pretty awesome. You may assume that the ability will go to a hero who has some dice in the required attack type, if any.
You can also rate abilities from the "build-your-own-hero" rules or other examples you find or invent, if you want. Just want to establish examples of strong, medium, and weak abilities by common consensus.
I realize that isn't a lot to go on; I'm not expecting brilliant insights or anything, just give me your gut feeling.
