You can buy champions with IP (in game currency) and not RP (real money). The only thing you can only buy with cash is cosmetics. All runes/champions can be obtained for free.

It's actually far more simple: follow Wil Wheaton's advice and don't be a dick. I'm Bronze (not al Rioters are good) and as you can imagine the toxicity is HIGH. That said it's not hard to not be toxic. Everyone has bad days, and you can't take it personally if someone on your team tilts. If it gets really bad just /mute them.

It's less about your game history and more about your behavior directed at strangers. We're a player focused company, and if you're a total jerk to strangers because you've tilted, how can you be expected to make the game better for those same people?

Made an account to just comment on this. It's not little stuff like passive aggression, or even swearing at teammates. It's the extreme stuff that gets you in trouble: racial slurs, death threats, pulling rank (I'm a Riot employee I'm going to ban you BLEEEEEEEP).
