When your Fiora feeds Rengar because...
I just came out of a game where the Fiora on my team had "mained" Fiora. Except when she came back, she was shocked to see that Fiora's kit had changed. Let's remember, the rework has been out for some time now, and Fiora now has a new splashart that's CLEARLY visible when you pick her in any mode, be it normal or ranked, draft, blind or teambuilder. So the first few minutes, everything's fine. I roam and get a double kill off bot, but the situation up in top? No one even knew until we saw Rengar kill us in like 3 seconds. Our jungler had tried to help Fiora, but Fiora knew nothing about the new kit. And continued to feed 0/5.
Now, I'm okay if you simply are trying to the new champ, but if it seems off to you, shouldn't you at least look at the champ if you see a new picture? And this is not even including the game choices she made, such as trying to take on Rengar when he was level 11, and she at 6. So when we told her to stop feeding, she says "What? I'm trying." I don't think so, but maybe my logic is skewed.
