I am not sure why people think the mechanics of multi rupturing are so awkward and clumsy. You just want to push one button and do meter topping aoe? We have very good sustained single target, bursty single target, with current 4pc.
You have to use a tiny bit of brain power to effectively aoe as a rogue. I guess some people just want one button to press.
Like Kym said, there are some minor QoL improvement that can be made, reworking CT is something they should look at.
