PBE changes are not final, relax.
Because there's PBE for a damn reason... to test changes. Jinx W doing too much damage? Ratios and/or base damage likely to be nerfed in the coming cycles. There's a lot of unbalanced stuff going through there that doesn't make it to live in the same state, relax. Just cause you dislike Jinx doesn't mean you need to go into a panic because of one buff. Same goes with Lux. Shit, Lucian's ult could crit in PBE for a couple days and that never made it to live.
PBE's not meant to be balanced, ffs. Reactions like yours can only discourage progress through testing.
