thanks for your advice, guys.
I finally won one. I picked Morgana. We had an AD Janna who built two PD first, and at one point all of our inhibs were down, but we came back to win.
I think my problems all stemmed from me trying to learn Tristana. I am a terrible AD carry player.
But, at least, I think I can do it.
Now I'm confident I can play whatever role my team needs, so I think I'll buy one more Rune page, and I'll finally be ready to start ranked. Maybe.
Not today though, gonna go see my family. Happy Thanksgiving, guys.
