Team comps can be retarded

So i just played the match in the link. We won the early and mid game. Then late, late game things just got retarded. I was 4/4/12 by the start of late game, and as you can see, i ended 4/12/20.

First of all, i did not pick Rammus, someone picked em and then we traded bcs i didn't wanna get stuck with the lane left. i wouldn't have picked Rammus into so many AP. Anyways, so late game this was the game changer....

Leona ult to slow everyone while in team fight, then Sejuani ult would catch 3-5 of us, then Kat ults in and by the end of her ult Zhonyas, while kat ulting Ziggs ults....

I am super upset that that match took 53 mins, we were winnign and still lost SOOOO freakign badly. Disgraceful man, i feel like shit. There was nothign i could do, there comp was just too strong.

I am so mad right now i was already on tilt i had lost my series twice to go to S3, after climbing from B2 to S4 in like 3 days. Now i seem to be doing terrible whenever i play support. And because of this match i feel even worse, like fvck this game right now man, so stupid hwo long that match was and how op their team was.
