I had a game

V.s.

I end up 1 /3 as Cait because I have a velcoz support who has no fucking clue how to use CC.
And zed is feeding his asss off to the midlane chogath. I catch up up, And then the guy starts trash talking me, Im useless, I do no damage.
end of game, graphs... I did more damage than him the whole time
