Well, I've really wanted 
for the longest time, shes so beautiful and underated, I feel if i get good with her, she can do very good, but I havn't been following the recent nerfs with her. If I were to buy her, would she be weak or would she do some damage? Just wanted to know if shes still a viable jungler.
She isn't good for solo Q. She is much stronger in coordinated groups.
No, shes not. And this is coming from someone with 150k on Rek Sai.
She is pretty bad currently unless you are very high elo where people know how to abuse her strenghts...not only the people who play her but also their teammates.
Barely, she is very macro play heavy and you need to be really good to play her. Not mechanically good, you just can't make any mistakes without falling very behind. There are much better junglers.
She's not underrated at all lol, she used to be the best JG in the game. After the nerfs she's not the best but she's still really good. She brings tank, CC, utility, mobility, and much more.
shes's really only good if your team can make use of her kit, she can't carry with damage
Not good, no. Worth practicing, because she has a great kit and will surely drift back into the meta someday, but don't take her into ranked at the moment.
after last nerfs ,she is not top tier jungler anymore.( wich she was ,since her release).She"s still very good jungler if you know how to play her.
Just start with cinderhulk instead of the recommended warrior. She's surprisingly squishy early game and really needs the health to not get murdered. And as the 2 previous posters said, a significant amount of her power budget was put into her tremor sense passive at the expensive of overall damage. In solo queue I'd imagine it would be difficult to capitalize on the advantages of that ability gives you compared to coordinated group.
as a lvl6 .. i can say.. she isn't.. she sucks right now. they actually buffed 
to pretty much do exactly what she does but better, just without the tremor sense. right now zac is pretty much just a better version of rek'sai.
Rek'sai is a pretty good champ. However, she's a macro champ. If you like Shyvana, then I would recommend picking her up.
shes currently visiting aatrox on a holiday away from the fields of justice
