I SWEAR WE ALL STARTED WITH ONE OF THESE CHAMPIONS
Let me tell you.
Veigar = you compared champion stats and found out that he supposedly has the highest magic power on profile. You then found out in game that he walks like a deformed child and instantly lost interest in playing the champion.
Malphite = you came over from playing dota and there's a thematically similar "champion" called Earthshaker. You liked the idea of jumping in quickly and reap havoc. Turns out he's nothing like the dota character.
Ashe = cute girl character, icy themed, and has this ultimate that just sounded/looked absolutely glorious as a noob player. I swear 50% of you chose Ashe as your first champion.
Blitzcrank = again, came over from dota and you know that the idea of grabbing is fun. Turns out hiss grab is so much shorter than in dota.
Ahri = another cute character and flies around with ultimate, shooting a heart. Charming.
Tell me I'm wrong
Edit: you guys all tell me you didn't start with above. Stop lying to yourselves.

but didn't have the ip ; Fiddlesticks was on free rotation at the time and was a "good support" so I'm more than sure I played him first.

because he reminded me of archons from SC2
and
