Keep in mind that most add the dice AND have an effect. They’re basically 2[w] and a kicker, which is well within the power range of heroic Encounter powers.They do not seem so much larger than encounter powers unless scales have changed a lot. Nothing like a marathon for sure. Heck most battle-masters abilities look almost like an at-will if they were spending one of the fighters attacks (instead of combining with it)
Plus, that die is doubled on a critical, and you don’t have to declare many until after you hit.
