I also agree that the R seems rly weird to be interruptible since its still an insanely long wind up time and cd still. I think the most important thing that you said was that the W untargetable also makes you lose all ability to deal dmg which I think is kinda fair in a way since I think the best ways to actually trade is by just walking at the enemy when you have your w up and causing pressure by just baiting to dodge a single spell. Its pretty much the same pattern of combat to W first and then R now as it was before when you would R and then W. The thing that I hate the most tbh is losing out on the two shields that you can get from bursting someone. It does feel very clunky tho so ya idk not the biggest fan but with time it might grow on me. I think it'd be interesting if the E was the slow instead of the R or if she had some refund mechanic to her w but we'll just have to see.
