WTF is league

I just had a game that personified everything I hate about this season. Got adc, went lucian, killed the laners, then killed khaz when he came down to gank. Went 10/0/somethin lane phase, got tier 2 by like 10-11 minutes. Then I rotated mid, won a fight there. TELL my team im rotating bot to catch this wave, keep in mind literally all of them are like 0/2, they pick a fight while im gone and all die. We lose two mid towers for it. Also suddenly the garen that left lane 0/2 is 3/2 and hence... unkillable. If he runs into my team he can kill any one of them before I can kill him AND still be able to walk back to his team before my damage is enough to kill him. My graves/tf duo make a random push at mid lane a few minutes later after I had just backed from picking off garen/khaz in a fight top, they get wiped for free for overextending, and the enemy finish the game off it.

TL/DR: You can leave lane hyperfed, but champs like garen will still be just as unkillable and deal fk tons of damage, even if they did nothing in lane. Khazix will still one shot you. And you're still just one overextension of any random idiot on your team who gets picked off for free from losing the game. Games a diceroll.
