Riot - any chance we can get a couple Sion tweaks along with the skin?

Is there any chance we could see a couple adjustments to make Sion more fulfilling to play when his new skin is released? I don't think most Sion players want numbers tweaks, but there are some long-standing issues with his playability that can make him unfun.

Examples of possible tweaks:

• change the minimum detonate time on W to go down with level, back to the original 2s at rank 5
• make his Q less painful to use by having it activate when interrupted instead of fizzle similar to Nunu's ult functionality
• reduce the delay when canceling his ult for early detonation by half to make it possible to sometimes hit sidestepping characters if Sion reacts quickly enough
• give his passive, or perhaps just death surge, a way to be a little more sticky. E.g. Give death surge a QSS effect, or make it at least remove slows or something

Personally, I would also like to see better AP ratios on his W and E. Right now, there really isn't a single AP item he should ever build, but it could easily be made into a viable second build path without affecting his primary build path much. Otherwise, maybe completely remove his AP ratios and donate that budget to other improvements.
