Idea for Taliyah
I've been playing a few games of Taliyah, think that she is super fun and balanced, but one thing that I found annoying while playing her was that you didn't know when the worked ground debuff would wear off an a specific piece of terrain. I think that worked ground is a really cool mechanic to work around, but I think that not knowing when that ground is available for full use again can make laning in particular feel like a guessing game as to when you can do things in lane, (set up for coordinated ganks, play aggressively, all in etc). I think a simple solution to this would be to illuminate the "ring" on the ground which indicates it is worked when you stand on it. And as the timer for the worked ground debuff goes down the illumination would be seen on less and less of the ring. Note that I don't mean illuminating the inside of the ring, I mean the ring itself, and then make it count down like a timer, similar to inhibitors.
