Hint, you are probably wrecking bots
. Up to lvl 5 it matches you and and your team against bots.
She is not OP, but she can be very good against new players. Her Q lasts 5 seconds and the invis gained lasts 3 so it is not a very good escape tool. If she uses F there is a very obvious sound that anyone close-by can hear. If she uses F to get close to someone, her best escape is now on CD, sure she might manage to pick someone off, but then she is an extremely easy target to take out. And her ultimate is not too much now, heck it's finally usable compared to how it was not that long ago. It is still very easy to escape unless it lands right on top of you and you don't have any movement skills. If she wipes a whole team with it, that says more about that team than her ability.
