Ranked Placement

While I get that it's pre-season this is kinda ridiculous. I finished my original placement games, seeded into Bronze V. Sure. That's no problem. Happens every season. I don't mind the climb. I know I can do it. But I spent two days playing ranked, climbed from the bottom of Bronze V into Bronze IV. I log on today, saw we have to play an additional placement game. Okay. Sure. I kinda felt hopeful, but I knew I had to be practical as well. Finished my placement game. Ended in a loss. Guess what? Back in Bronze V again. So what was even the point of all those games I played climbing from Bronze V to Bronze IV? I mean I know I can do it again. But it feels like those two days were wasted. And I'm feeling a bit frustrated too. :\
