On one hand I'd tell you don't team fight and instead be splitpushing.
But on the other hand, Yasuo team comps are generally ALSO the kinds of teams that get to decide if a team fight happens or not. And turrets don't do shit to a Malph or Alistar past like 15-20 minutes so you can't stall, so splitpushing would more than likely just mean getting oblitorated 4v5 or 3v5 under tower and then they wreck that lane way harder than your split pushers do in theirs.
Honestly given how easy it is to synergize his dumb ult with another lane it has no business having a low cooldown, especially not the ridiculous 30 second CD it has at rank 3
