I like the PBE Varus Nerf.
- Q CD increased to 20-12 from 16-8
- Total AD ratio lowered to 1.5 from 1.65 for max damage
- CD is reduced by 5 seconds flat if the arrow detonates Blight stacks on a champion
Basically, this nerf specifically targets the unhealthy long range poke Varus (Lethality Varus). Which, btw, is not just a problem of this season - ArPen mid Varus with Youmuu's, Muramana, Maw, Last Whisper Upgrade was already a common pick in LCK last year.
Also, the CD reducing effect emphasizes the importance of CdR for Varus - 40% CdR Varus who procs Blight with his Arrow gets it back in 2.2 seconds!
What I don't like is MF's Double Up changes (if the 50% bonus damage is too much, reduce it). And Jhin still needs his legs broken with road roller a real nerf that is not merely a love tap. For example, by having his base MS reduced to 325, like all the other long-range Marksmen.
