Jayce Bug & possible eq interaction qol

When you e in hammer stance doesn't show the cd sometimes much like azir's q.

Also when I put my gate down then mouse over an area and press q, then mouse over somewhere else to continue csing or move, the q feels clunky in that it wont seem to register that I pressed q until I move my mouse away from the initial desired area. (I hope you could follow that .__.)

I hear that you can q e instead of eq for a smoother combo. Should I be doing this instead?

Additionally I think his q goes the max distance it can, whether through his gate or normally regardless of where I mouse over (or this could be also the problem above)

Hopefully the boards version of this forum is more active.
