Patch 4.20 is the greatest thing that happened to ARAM, since matchmaking
- Sona's sustain nerf (Her win rate dropped by 5%, and she's still #1 - it just tells you, how ridiculous she was)
- Chalice and Grail nerfs
- new items, that are just fantastic for melee (Righteous Glory, Raptor Cloak)
There are still many stomps, but overall I feel like ARAM is better place now.
