First off, if you're just going to ignore everything I say and pull a strawman on me, I'm not going to continue with this for long.
Second; You're expected to play the game out. You're not expected to win, you're just expected to play to win. If that means magically pulling a Trinity Force out of your ass, so be it, but you better have your wand ready and make sure you got the rabbit out of the way first.
I just gave you perfectly valid suggestions for how to circumvent the lane tax and maintain some reliable form of gold income. Advice which could actually put you in a position to make an impact despite the trolling Nunu. You may not win, but you'd at least still bounce back.
And, again; all of this is beside the point, which is you are not allowed to leave a match before either Nexus explodes, and you are not allowed to flame other players, regardless of circumstance. If you don't like it, them's the 8r8ks. When you play League, you play by League's rules, so if you don't like the rules, you're absolutely free to not play.
