I don’t know about your flashes but one way to balance your would be to let waylay have 2 refracts and let your gatecrash and refracts have the same duration.
Personally i think refract is better in terms of escaping danger and increases waylay’s dive duelist potential.
But we will only see waylay become meta if the light speed is made into the refreshable util and she still can start with 2 refracts.
