Hop in Ranked, first game in a while...Lose more faith in this game

I don't understand why people have the thought process to pick a squishy adc top when the only somewhat form of tankiness is either me or Morde. We had enough damage with our setup. Now, it probably would've been fine if the Twitch didn't also feed Tryn a couple kills enough for him to kill our somewhat fed/strong Morde and provide an overall threatening presence of pressure. Let's not forget their Irelia who's good as the game goes on cause she's Irelia and bot lane also somewhat losing.

I couldn't even finish Trinity cause I had to side-track to make a Randuin's so Tryn wouldn't just screw my day up since he had free-roam capabilities. It blows my mind that his ult is still the way it is. It does not blow my mind that people make stupid decisions like Twitch top. It maybe would've been fine if balance was actually taken into account...but this is League, so it isn't.

Is Riot even trying anymore? Or are they just riding on a highway to the death of this game?
