Riot, Rek'Sai is now a Top laner. Just like the past two Junglers.
For the past Summoner's Rift games I have been in or spectated, Rek'Sai has been sent up top and has been very successful. Jungling Rek'Sai players have either fallen behind fast or have no idea what to do due to her frailty in the jungle.
Is this something you have planned or looked at? For the past 3 "Jungling" champions, none of them have been seen as a primary jungler and have been having more success in the top lane. Aatrox is rarely used, and when he is, it's usually an AD top. Zac is another top laner used due to pro-plays. And Rek'Sai has more success overall with her build for damage in her kit in top lane than she does in jungle.
I'm not upset that these champions are seen in other lanes. In fact I enjoy a variety of roles and paths a single champion can take in the game. But the recent junglers just don't seem to fit as strongly in the jungle than in top lane, at all due to their odd stat scaling and kit, mainly the regenerating passives.
