What if there was a character that could fake an ability? Like once per round or so he could throw a fake Raze nade or put a fake cypher wire. I think it would add something interesting to the game, and it would make players use their brains.
I think another cool idea would be to be able to fake ultimates as his ultimate. For instance if he has ult and a friendly Raze had ult he could ult and her ult sound would play, and her little indicator would turn green until the ult is over, it would add more mind games to Valorant and I think it could be interesting.
