Rune change/Balancing

Ok so I know it may not seem like much and might sound like another complaint that isn't all that important, but I truly feel like the rune change has made the game too unbalanced. Don't get me wrong, I love the change and think its super cool and fun, but some champions have gotten a little too buffed from it. From my experience Nasus is the big fish (hah, not Tahm) who keeps crushing every match he's been in. The ability for him to 1v4 is kind of ridiculous. Other than just regular Nasus complaints, the tank meta is out of hand. Tanks are cool and all, but they do need a nerf overall in my opinion. I love the game, and even though I'm not very good at it, I hope you take what I said into consideration and keep the game flowing with imaginative content for everyone to enjoy!
