Can we talk about Quinn's ult?

So I've just recently picked up Quinn and started to play her and I love her! Much like the few other people who love and play Quinn. I'm worried about her new ult. I like the idea and everything but I feel she's at a disadvantage compared to the other adc's. Her ult is no longer a way to quickly get into a fight and kill someone. It's more of early homeguard than anything. I understand that it doesn't have a cool down but that 2 sec cast time is going to ruin Quinn's fast and agile play style. No longer can we jump off someone's face and fly away. We just have to hope that we see them before they see us so we can ult and slowly fly away. Also she doesn't have her blind in the new update which is going to destroy Quinn's ability to fight another adc. Normally in the early game you would blind an adc to stop them from winning the trade but that's now out of the question.

Basically I'm trying to say that I'm really afraid of the new preseason and I'm hoping that Quinn will still have that "I'm a scout that can fight anyone" feel.

Thanks for hearing me out. Also I don't have full knowledge of Quinn's rework so I'm probably just overreacting
