Malphite stomping Darius are you out of your mind?!
First of all, I don't even know why you think a tank should be winning laning phase against a bruiser.
Have you played tanks in the earlier days of league?
You know how their laning phase was?
About as weak as current GP or even weaker (without having a spammable ranged spell keep in mind).
They would literally sit back, do nothing and hope to get 5 cs/min (kind of like Nasus back then)
And you know why they did that?
Because they scale GODLY into teamfights.
They are propably the best teamfighting class there is (guess why you see 4 tanks per game in pro-games)
So now you come here and in all seriousness tell me that they should be auto-winning the laning phase AND have their ridicolous scaling?
Are you working at Riots balance team by any chance?
If anything, you need to actually nerf tanks even more and I'm not talking about +0.25 seconds or - 5 base HP nerf, no I'm talking about upping their mana costs, uppin their cd's in early levels, reducing their base stats in early levels, nerfing the tank runes and nerfing their base damage and upping their ratios.
That MIGHT fix tanks but Riot has a hard on for braindead tanks so they are going to stay god-tier.
