The new visual effects cause issues when you combine these two. Depending on which order you cast them, the Shuffle transparency effect will not be present.
Quick Cloak followed by Shuffle => no transparency visual
Shuffle followd by Quick Cloak => transparency visual
Makes it really hard to track if your buff is up (good thing us PC players have decent addons to fix that), but this will cause big problems for Console players, who are already playing blind most of the time.
Also reported issue in-game.
