Don't forget the suggested enhancements to mine field and throw mine I suggested... That would be the real hypothetical MVP. I think the Slick Shoes stunbreak is currently awesome, the speed lasts for a good amount! I'm not sure Stability or Ammo would be my first choice to improve it. We just put long stabilities on Defense field and Elixir U. If I was going to nudge Slick Shoes toolbelt, I would allow the Engineer to suppress the effects of immobilize while under the effects. But I don't think we need to buff it if the utility portion is good enough to use. Now there's something. If Goggles becomes the stunbreak with short immunity to blind, weakness, vulnerability, whist slickshoes toolbelt stun break grants superspeed and short immunity to cripple, slow and chill. Both are thematic to the utility, add value to their practical function and aren't to0 strong :)
