Add a little power to the Powerball?

I know that people suggest this every now and then, but I'll bring it up again: Why not have the damage, or at least a portion of the damage, from Rammus's Powerball (Q) increase as he picks up speed? I think it would fit well with the existing Q mechanics, if not with his whole kit (which is kind of on the weaker side thematically speaking). I don't think it should necessarily scale directly off of his move speed, as that could lead to some absurd Rammus railgun one shot kills. We've all seen the Sonic Rammus videos. He goes fast. I suppose you could cap the speed damage, but I think a better option would be to have a damage amp that matches the move speed he gains from Powerball specifically. Maybe the base damage could be lowered a bit and, as much as the full AP side of me pains to suggest it, the AP ratio could be as well and then the damage at max speed could be a little higher than it is on live. Overall I think it'd be a pretty simple way to give him a little more variety in his gameplay. Instead of Q-Flash it might make more sense to try to chase the enemy down. Or you could rev up in the brush for a little bit more oomph when you go to gank. That's my two cents. looking forward to some other views and ideas amid the sea of OKs.
