KevinIsPwnPeople complaining about the shortstop probably haven't tried it. If you got close enough to actually do that to anyone in a competitive game, you'd just be feeding.
Agreed.
If you're close enough to shove someone while you're playing with the shortstop you're already doing it wrong.
If you're going to constantly be so close that shove makes any difference, you should just be on scattergun, so you can hit 100 damage meatshots instead of 70 damage meatshots.
As far as the shortstop's style of play is concerned, they just lost the +healing buff in return for nothing. Essentially a direct, un-needed nerf.
