Mine was Caitlyn. After playing with Ashe up to around level 5, I took a look at every champion available at the time; Caitlyn looked like the best choice to me. I still play her to this day.

Nunu was my first

Soraka.

Morgana because she was on her free week. She started my love for AP mid. =3

My first champion purchase was Janna because she was the prettiest of the champions I could buy at that moment. Played her building AP. xD

Mine was Malphite, suitable for any lane. It was free the week I started playing, but still didn't unlock

Alistar!

When I first joined I was practicing with bots and saw how much cc Alistar had and I bought him right away.

Shen because he was free that week, Ashe was the first I bought and then Teemo was the second.

graves i now play with olaf

Nocturne, I don't play as him anymore though.

I find it way to hard to think back that far but my oldest memory of this game was playing with my other 2 friends on TT as fiddlesticks. I ultied the minions to see what my ulti did which was swiftly followed by the laughter of my friend
