no changes to the tiers this patch but still stuff to talk about:
Alistar buffs are really big, helps him keep q cooldown similar to his W allowing for less downtime in his combo. not big enough to make him s tier though.
Pyke buffs are great for his laning, making his roams worse, pyke issue wasnt his roams it was his laning so good buffs.
Ezreal nerf buffs all in supports like alistar, naut, thresh etc, blitzcrank.
Karthus buffs in BOT makes Janna + Karthus viable again.
if you are duoq you can run ghost on the adc and have yuumi have heal exhaust if barrier / cleanse on ad isnt needed.
green = easy | blue = medium | red = hard
