@Meddler on Syndra's Q (and any other ground targeting abilities)

This is my first boards post so be gentle.

Syndra's Q is a ground targeted ability where she will create a dark sphere at the location of the cursor. There are plenty of ground targeting abilities scattered throughout the champions in league, but it wasn't until playing Taliyah on the PBE I realized not all of them are created at the location of the cursor. For example, if you cast Taliyah's W outside its max range, instead of walking to where the cursor would be it is cast at its max range in the direction of the cursor. I feel like this would help Syndra a lot. Sometimes she feels so clunky when you try to cast her Q just out of range and she has to walk (well, float) closer to cast, especially since casting her Q doesn't interrupt previous commands. This was also add to Fiddlesticks' R and it feels a lot better.

I understand that for the point of precision, not all ground targeting abilities can work like this. It could feel really awful if this were the case for Ziggs when he cast his satchel charge and he missed a really good knock back due to not walking up and casting where the cursor is.

What do you guys think? Are there any other champions with an ability like this you think will feel smoother if it was cast at max range instead of walking towards the cursor?
