Kassadin, Maokai, Poppy and Yasuo don't have scaling Magic Resist
Riot has been making the champs that scale or do not scale with Mres more consistent based on whether they ahve ranged auto attacks or not. Hybrids such as Kayle, Jayce and Nidalee lost their Mres/lvl while melees such as Shen and Singed recently (finally) received theirs. However, there are still 4 melee champs left in the dark. But do they currently need it?
actually used to have Mres/lvl but this got removed as his first nerf during season 3. Kassadin was ridiculously OP and his kit was broken, so they nerfed every aspect of him while keeping his "identity blink" until they figured that they had to nerf his mobility. So they started nerfing his ult many times. What they forgot to do, however, was reverting some old nerfs that are now just unnecessary or overkill. At 42% winrate, he is currently one of the 3 worst midlaners in soloQ. He's supposed to be an anti mage, but currently he only has a magic resist shield on his Q. That doesn't protect him from the constant harass he receives. Bringing back his Mres/lvl seems incredibly logical to me. An anti mage that has a very low winrate against most mage champs is pretty odd.
is in an okay spot right now. He sees play in the competitive scene because of his utility. In soloQ, however, he's slightly under average with a nearly 49% winrate. Maokai doesn't really need the extra Magic Resist, but since he's not dominating atm and he's a tank, why not? It makes sense. The only reason Riot may want to hold him at a flat 30 is probably because of his already high appearance in tournaments.
is getting a huge rework. I'm convinced she'll get scaling Mres with that rework. Atm, she's doing under average but her kit is so toxic that no one really wants to see her buffed.
is actually in a pretty good spot right now. His winrate is about 49% in mid and 51% in top. For a champ that partly relies on teammates having knock ups to set up his ult, I find this winrate quite a lot for soloQ. He does have a wind wall and his dash to block or dodge magic abilities. However, since his mid scores are worse than his top scores, it seems that he isn't doing great against mages, while he's supposed to. I think adding the Mres/lvl is the first buff he should get incase he needs one.
tl;dr Kassadin obviously needs his scaling Magic Resist back, Poppy needs a rework first and hopefully gets MR/lvl with it, Maokai and Yasuo are currently in a good spot and don't need a buff atm, if they ever need one, however, giving them MR/lvl to put them in line with all other melee champs would be a great way.
