User blog comment:Willbachbakal/(Champion Concept) Meenk and Scruffy, the Big Game Hunters/@comment-6061249-20130816112829/@comment-1330314-20130816144651

I wanted Scruffy's heal to be flat across all ranks because it's only just there to make him combat-ready. Too little, and coupled with Scruffy's low health the latter dies too quickly. Too much, and Scruffy becomes an even better tank than Meenk, especially if building tanky.

As for his leash, I don't want to give Scruffy unlimited movement range, as that could lead to a lot of abusive cases (sending him to clear the red buff while you get the blue buff, for example, or pushing a lane from your base). Currently the only champ who can AFK push/harass is and Riot is planning to cut that out of his rework.
