Suggestion: Casting Q on Worked ground reduces the duration of select worked ground by 1/2/3/4/5 seconds.
Taliyah is very much a roaming champion naturally, however when played midlane it's not uncommon to see the use of worked ground Q's in lane as poke.
I personally think having her Q reduce the CD of her Worked ground by a few seconds each cast would be beneficial.
This incentives more lane interaction with her laner as well as not buffing JG. As many would know, JG Taliyah rarely reuse the same WG patch.
