In my opinion he has to be reworked (it won't happen cuz hes not that old), or hes abilitys changed dramaticaly. Becouse if RIOT gonna buff hes q agen, like it was before, people will cry about him being broken as shet. If they gonna leave him alone, people gonna cry about him being to weak and unplayable.
P.S You can find some pros videos, who are able to make him work in the top lane, I'm not even talking about jungle...
In the past I did liked khazix a lot, but after hes nerfs, everything changed. I miss my little bugy.. :/ [zombie-nunu-tears]
