needs to lose her burst, indeed. Plain and simply changing Q to a smaller buff for several autos should do the trick.
could use a look with her annoying traps.
needs a nerf. In fact, he needed one for the last 5 patches.
needs to be observed. Could be that he needs a nerf, similar to Vayne.
doesn't need changes for now. She's stable between 49 and 50% winrate for patches. If she's going to need something, they could look at her base AS - upping that to .640 or so should help her some.
could use to have her 6.18 nerf, the one to W's cooldown, reverted.
is currently excelling while being played mid. I don't think that he could be buffed for the ADC without being bonkers there...
Personally, I'd trade some nerfs on her othe abilities to her her former passive's values back - namely, 9 range per level instead of 7. Or change her base range to 525 on level 1 and give her 10 range/lvl.
like Corki, he is currently rather strong in mid. If they wanted to buff him for ADC, a good thing imo would be to increase his base range to 525 or even 550, while keeping the empowered values the same. Other than that, 6.23's buffs to Rageblade and BotRK should help him some.
also no longer a bot lane ADC. For her (and I say that as a main), I'd love to see them lowering her early power (by increasing Harrier, Q and E base CDs by 1 second each) and give her a bit more power later (have her ult passively decrease Harrier, Q and E base CD by 1/2/3 seconds).
