What tilts you beyond belief in Soloq?

I recently won a tourny, which playing on a team made me realize that this game is a very different game than the good ol' solo q makes it out to be. I'm not bragging or anything, but playing on a team was actually a lot of fun and enjoyable. Going back to solo q was literally hell though. What tilts you guys out of minds when playing soloq? For me just some things I saw in ranked from the last couple of days:

-When someone picks ashe support. -Your win condition is to group mid and win an easy fight? Nope, Morgana splits bot lane making it harder to push mid lane. -Whenever someone on your team picks Garen...just dodge when you have Garen on your team.... -When you loose your 15 game win streak to Urgot.

Well...now that I'm done raging, I guess it's time to go back at it and earn that elo...but I swear for the next wannabe Vi support, please leave that crap for normals.
