Well, except Vulnerable's always 25%, and there's no guarantee that the Vulnerable from Infra-Sight will do anything to the heroes. For all WM knows, they're back in their base, chilling. In a teamfight, though, it's just another damage ultimate in terms of damage potential. It's no more powerful than Nova's Precision Strike, Xul's Poison Nova, Li-Ming's Disintigrate, or Valla's Strafe, just as a few examples. At most, I would increase the cooldown on Infra-Sight by about 15 seconds.
