There’s not a single role that I would consider bad for Tali. Yeah she might not be the greatest top laner, but she still has so much mobility with TP, ult and passive, and she scales a lot. She has become my default auto fill pick regardless of the role.
Back in the day lulu used to be an actual viable pick in all 5 positions
AD/AP Lulu as top laner
AD Lulu as jungler
AP Lulu as mid laner
AD Lulu as adc
AP/Sup Lulu as support
There was actually a point in time when AP Lulu jungle was popping up for a little while, this was like Season 5 or 6 or somewhere in there when people were playing random stuff like Ezreal jungle too
