Just simply - nope.

"Dealing or receiving damage from any source (including champions, monsters, towers, and minions) counts as combat and will result in the base movement speed bonus of 25."

That means unless you hide behind your carries you receive damage. This is pointless to discuss.

I think we are talking about different things and its coming to simple yes-no exchange. Of course, some of your points are valid, but already mentioned or obvious.

Maybe you can try at least put example of such a champion - initiator. Mentioned champions are just more fighters, one target-pick than initiators, only Amumu has huge ultimate.
