Rek'sai needs to be fixed ASAP
Just played a game where Rek'sai went AP mid. The ONLY AP ratio that Rek'sai has is her Q. Which has 100% AP ratio and ~1300 range. With no resource to worry about managing, Rek'sai can just sit outside of turret range or in bushes near mid turret, be able to clearly see where i am because of tremor sense, and just Q away to her hearts content. No risk involved. No real counter. Just safe poking. FIX THIS RIOT. DO SOMETHING.

or
AP builds. Idk guys I think it's all preferences and just nobody understands how to counter each build on the new champ yet.
