Taliyah is being to feel like Kalista, Ryze and Azir
Don't get me wrong, I love Taliyah. She's my favorite champion in the game (Although not my most played but I digress) and I've played her since release.
She's been a VERY controversial champion Balance-wise. Coming out of the PBE overly weak, only to be buffed and changed to pro-play dominating levels, to nerfed to reworked into a jungling monster into being adjusted into her current low playrate (But still unfortunately high winrate). She dropped 8% play in the most recent patch
Taliyah has appeared in 26 SEPARATE PATCHES since release, only 4 of which were bugfixes. She's also been hotfixed on MULTIPLE of those occassions. Considering all of that she is STILL not much closer to being a consistently balanced or viable champion.
I feel like Riot kind of just needs to accept her Kit isn't going to be a high playrate kit of success and just set her down like Kalista, Azir and Ryze so they can turn their attention to other more warranting champions.
