Lets nerf Jinx! But not the way the PBE is doing it.
What will the PBE changes really do to Jinx? She'll still be able to be very effective with everything she does, she just won't have her ult to burst people point blank range. She'll still have her current scaling pattern of being decent at the start of the game and then scaling up to a hypercarry without ever falling down or having a very vulnerable phase in which she can be shut down.
Instead of going on about stuff, proposal: Instead of changing Jinx's ult, Jinx's rocket launcher (fishbones) is no longer able to crit on all targets in blast radius, only the target Jinx targets.
We all hate crits, and AOE crits are a nightmare. This lowers Jinx's hypercarry abilities somewhat while still keeping her viable, and also lowers her late game waveclear allowing her to be played around against a bit better.
