Man I just got done raging hard.
Farming up top as PL, getting great early farm, 3 kills/lots of CS by 10 minutes. Bot is doing fine, mid is winning. Our mid, QoP, buys a gem at 10 minutes, procedes to gank Slark who was top and had NO FARM, died 1 or 2 times, and was no threat, and QoP dies. Loses the gem and we never get it back. I get ganked multiple times, we also have Bounty who is completely fucked all game, forced to get an early BKB because they see him in every team fight.
I'm pretty sure I had temporary insanity for the rest of the game. It really seems like a dumb idea a child would have. Lets buy gem, instead of any amazing QoP items like sheep stick, to counter one underfarmed and semi shitty hero. No worries that our team has 2 invis heroes and will possibly get fucked.
Also, this QoP then bought Dagon 5.

Edit: Oh and his buddy who laned with me, stood up for him saying my farm was shit and I was slow. Good thing bro code doesn't let your friend know that he single handedly lost us that game and maybe give future tips on how to give a game away.
