Rek'Sai I think this new champion is good for escape and ganks. E is something like dash or teleporting and i like it. But he isn't such a good damager, but i think he is good for ks or something. Also he is rly good jungler.
Hmm, I suppose he is not so strong. Just have game where was 2 Rek'Sai's, one was bad, other was a little bit better. May he can be good tanky/ad... Holes are good and can help with ganks.
Yes, he can good escape with this holes, but for gank is harder, you must play longer and study his better..
Playd her and i can say she is tough but a lot of fun.You will need to learn the specific mechanic but she is OP if you can master it
