Mundo nerfed , i assume because of all the antiheal cut nerfs, he can still farm safely with Q and kinda not int ( good autofill tank pick imo ), still fine champ but down a tier, also because champs like fiora is being played alot which mundo dont like, mundo likes being vs GP Jayce type of champions.
Fiora down a tier, still very very strong in the right hands though, dont stop playing her.
heimerdinger buffs very good for top, sucks theres alot of fiora, irelia etc players atm which heimer dont like, vs heavy melee comps like tank melee top and melees somewhere else heimer is very good, he also does well vs alot of range tops like GP for example.
singed is OTP champ, i dont care, if you are OTP play him no matter his strength, if you arent otp, pick singed into ornn or some shit like that
Harvester is mainly good for Gragas id say when you want CDR AP gragas, buy a tear then go harvester and then go seraph, i still think everfrost is good some games for the self peelbut if u want nuke and cdr you go harvester
predator nerf is huge for singed aswell, fuck u singed otps >:-)
Malphite down a tier, people being more tanky means less oneshots with ur ulti both in lane and outside of lane, there is less jayce ( one of his best matchups ) still very good vs low mobility ad heavy drafts.
Gragas up a tier, good buffs to him both directly and indirectly
