Full Tank Garen OUTDAMAGES Full Damage Carries

I have yet to see a SINGLE game where Garen did not deal the most damage on his team, despite building FULL TANK.

Sure, he's a damage tank, I get it. However, he should NOT be doing more damage than full damage carry roles, like ADCs, AP mages or assassins. These last 3 roles die VERY easily if caught out, but as a tradeoff, they get to do lots and lots of damage if played right.

Garen gets to do lots and lots of damage, more than his carry teammates, but is not squishy.

In fact, I played Vel'Koz the other day. 3 of my items were Void Staff, Liandry's and Rylai's. I completed 5 spell rotations, and I still could not kill the Garen that was running at my face. I went OOM. I could barely kite him with Rylai's, my Q slow, and my knockup, and when I went OOM, he finished diving on my face and killed me.

Sure, you can kite him and peel him, but he is SO TANKY that eventually you run out of mana and CC spells to even kite him with, and he builds Dead Man's Plate and Boots of Swiftness with Alacrity, plus he has a movespeed boost, so eventually, he will catch you and kill you, and not even hiding under your tower will save you late game.

So please lower this guy's damage, or nerf Dead Man's Plate, or something.

(And yes, Skarner suffers from a lot of the same issues, but he's getting a hotfix nerf in a few days. However, Garen on the other hand is getting a SLIGHT movespeed nerf and a damage BUFF on the PBE.)
