So im a jungler, i main rengar, qiyana and nidalee so i dont think rivens mechanics will be a problem for me (i might get humbled though) but i just have to ask is she viable in jungle? I want to learn/play her but im a horrible laner so i wont play top where you can go 2lvls behind just by recalling at a bad moment. Also What are the most important combos to practice?
