Melee champions should get at least 5 MR
Back with the old runes you were having 3 options
1-go for the standard 12 MR blue runes 2-go for the late game 27 MR per lvl blue 3-Go for CDR per lvl and focus on snowball and risk to get shutdown early from AP enemies
But most of the times you were having 12 MR or 24 at lvl 18 from runes..
Right now you have 0 OPTION for MR runes unless if you go for the "tank" rune that provide 5 MR..or for the one that gives 8 AFTER 10 MINUTES...
That a problem..lets say you play i dont know a what ever champion that its melee top lane...and you have a range Mage against who would play this match up with 0 MR runes with old runes? NOBODY..
So why Riot didnt add a single MR bonus to melee champions? but in the same time they buff the magic penetration...sure you lost the 8 Magic penetration from runes but even without that magic penetration a mage still deal more damage to a champion now because the champion dosent have the 12 MR so even with 0 buff to magic penetration a mage would still deal MORE damage because 8 magic penetration mean it remove 8 MR but with the old runes the champion was having 12 so he was still having more MR than your magic penetration but now he have 0 so i dont see why riot buffed the magic penetration...
But beside that Why there is not a single MR bonus on melee champions? why i should go vs teemo or kayle or vlad or liss or singed that have ARIE for mastery and i cant even do nothing in lane?
And dont tell me "Oh mage sucks now dude wtf you say" No the biggest win ratio in mid lanes belongs to mage champions...ok? and the top lane has become a shit hole...you ether face a stupid tank like ornn that riot forced to be OP by making his damage max hp or some teemo or kayle
For me riot should give to melee champions a 5 MR bonus or a scaling MR +1.2 MR per lvl extra on melee champions its still weaker than the old runes but its something to help the melee champions but the 5 MR bonus for start it would feel actually good
And NO i dont care about yasuo or zed dont blame melee champions because riot dosent know what to do with yasuo or zed..and zed actually the problem is not the champion is duskblade and lethality that a whole different story...
