Quinn's Passive
Just a small idea, but I think it would be a nice change if could see the timer of our next harrier. It should be a small buff icon or a cool down timer on the harrier picture. That way, we can see the next harrier and be able to coordinate better with it.

Also, the wording for the passive is probably a bit too vague for people who have never played Quinn before. The description for the skill is, "Valor periodically marks enemies as vulnerable for 4.5 seconds." It would be nice if an exact number was given, instead of the word "periodically". The way the passive is described doesn't quite properly explain how the small nuances of the passive works.
