Perm Banned for Intentionally Feeding a 15 minute game

Hi,

Let me start this off by saying I 100% deserve a permanent ban for my mouth :)

I got banned for "intentionally feeding" a 15 minute game where i went 2/3/1 in. Saying this, there are reasons where I should've been 'banned' for this game, but I think even those reasons are fairly light. Being it's the pre-season I thought it might be fun to go top with a targons brace and try a shaco duo lane (sure not great idea, but im not intentionally trolling her either, it's not meta anymore to have a duo top but I have targons and im not stealing her cs) after irelia verbally refused to help me out leashing (poor choice on my part, but thought it might be fun). she instantly runs down top, then mid, and leaves the game.

What I don't understand is why this game leads to a permanent ban ( shown in client as the ONLY game used to support that decision ), during the pre-season while people are still trying things out with runes/masteries/turrets etc.

I can definitely understand other games I've had where I could be banned for saying extremely shitty things to other players after getting worked up over the game. However, I don't understand how she would not also get a ban for this behaviour and I highly doubt she would've the same punishment I got.

Not saying I don't deserve this ban, but I think it should be more for my mouth, then my actions. as I certainly am not an intentionally feeder on the regular deserving a permanent ban.
