You can play Taliyah in the jungle and mid lane right now and that's really fun. Playing champions in multiple roles is really cool especially when looking at the enemy comp and you have to figure out who goes where. Champions are supposed to be given a kit and then put into whatever lane people feel like and not given one, if you force Taliyah out of the jungle and just as a mid laner that's super streamlined. I don't see any reason to change her, she isn't op in the jungle and is just a strong pick right now. If you aren't going to destroy Graves then you shouldn't destroy Taliyah. Taliyah jungle in the LCS would be awesome, not the other way around.
