Please don't leave a blank line after each sentence. It just adds unnecessary length. Thanks.
Ran, some quick napkin math showed me that my slam is still higher damage per rage than a 20 rage cost heroic strike on a target dummy.
This was very quick napkin math done by doing 30 slams and 30 heroic strikes with the same buffs up, then dividing the average result by the rage cost (or theoretical rage cost in heroic strikes case).
I did the math with Slam costing 20 rage instead of 15, as I wasn't 100% sure what we loose in white damage from casting slam.
In my current gear with no buffs, slam was doing about 652 damage per rage, with heroic strike doing about 233 damage per rage at 30 rage, and 356 damage per rage at 20 rage.
I'd wait for smarter men to confirm though (or I'll do more when I have more time).
