Sadly, Juhani is pretty useless. She only has marginal use in an all OR squad as a second tank and cleanse.
JKR doesn't really need another cleanse. JKR doesn't often even need a taunting tank. When JKR was meta, taunting tanks weren't even useful since JKR goes around taunt and Jolee has a "you have to kill me first" taunt.
Ultimately, her 4 turn taunt is dispellable and then she sits there useless, though. That is her downfall.
In this game there are precious few tanks that get used that aren't a pre-taunt or triggered taunt. Only one I can think of off the top is St Han, and he is fairly niche. I guess Old Ben also, but he is mainly used for his Mind Tricks and not for his taunt.
