Vyse ult is not that overpowered

I just saw a post with 1k upvotes saying

"You see Vyse is one point away from ult, you buy a Ghost just in case. She gets ult but doesn't use it, you die and you just lose $500. Then you have to decide next round if you want to buy another secondary again just in case. The longer she holds onto her ult, the more likely enemy opponents overspend on secondaries that end up not being used in that round."

That just seems stupid to me, I mean it takes away primary for 10 seconds. In that time you can just use your util to stall. Is it still a decent ult to basically force the enemy team to use util? yeah. but its not that overpowered and isnt gonna force you to buy a pistol every round she has ult or something idk why people keep hyping it up so much.
