IMPORTANT - Quinn update!
Quinn is, in my opinion, an amazing marksman. Her kit combined with her ultimate which swaps her out with Valor in the field is just great and to be honest very fun. However, I can't be the only person who would like to see a small ability buff somewhere whilst Valor is on the field. Seeing as Quinn is primarily an ADC marksman, ulting and changing to a melee fighter instantly changes everything about her. I think what I would really like to see is a rework to her E - Vault whilst playing as Valor.
Whilst playing as Valor in the field, Vault traditionally jumps to the opponent applies a slow, a small knock back and physical damage. Then 8 seconds later she can do it again. This is an ability which takes an ADC marksman and places them directly into harms way which completely negates all traditional ADC methods (which I still absolutely love). Although I love it, I do not think the reward matches the risk of the ability. After some thought, I have come up with a viable solution. It's simple, on kill or assist Vault is immedietly reset whilst in Valor - It only makes sense. Vault, whilst playing as Quinn has an additional feature of leaping off the target to the maximum auto attack range and marking the target as vulnerable for the harrier passsive. As valor you lose the security of the leap and the additional damage from the harrier passive.
SO, what I suggest to Riot is to consider adding something which should have always been there. Simply add to Vault - Whilst playing as Valor on kill or assist the cooldown on Vault is immediatly reset, allowing her to really move into that assasin role whilst surrendering her marksman capabilities. Because this might be to strong, they could nerf the damage output from the ability whilst playing as Valor. Just food for thought!
Let me know below what you all think :)
