It would definitely be better if CC got overhauled after any potentially troublesome champion got dealt with first, but I don't think the order in which the above changes should be made really affects the core message.

If necessary, it would always be possible to give Phase's components separate durations, but I'm personally strongly against that, since I want the combined immunity itself to be a consistent effect. You're right that doesn't block CC, but I was referring to Kayle's invulnerability while ulted: she can make herself ignore damage for up to three seconds, so when she gets to kill targets within those three seconds even when not ridiculously fed, she becomes a problem.
