Just because we're fed & winning, doesn't mean you can feed with no worries
Played a game as Thresh support, and our Fiora top was doing bad against a Cass top (seriously people, don't do this...). When they have reached around level 6-8, Fiora was left being 0/6, and accepted the offer to swap with our mid laner. By around the 20 minute mark, we're at the advantage with a better gold income & more kills, and our Fiora managed to boost to 2/7. We managed to suppress the enemy into pushing themselves into their own inhibitor turrets, and after we backed, this is where it all started.
You see, back when Fiora was still at top & was getting constantly rekt, she didn't bother to say a word & says stuffs like "can i get a gank pls" like any normal person does. But after the situation said above, she started a habit of pushing lanes with no vision at all, dies & started saying stuffs like:
"pls, lemme cs D:" "aww dang it" "oh u so ded"
And according to this, it looks as if Fiora is a bit TOO relaxed. As if she doesn't give a damn about her safety anymore compared to her top lane experience, nor her team's concern of enemy team being able to rack up more gold. Fiora just thought that it would be okay for her to fool around since we can finish the job easily without her. Well it's not. My team is still focused on not splitting up, I'm still keen on putting wards on specific spots for our team to locate for safety, and our Fiora was just being "meh u guys got this" & dies again either by going to a lane with no vision, or suddenly tries to 1v3 for no apparent reason.
And what happens next? You guessed it. After she died again, her team manages to get a grip on us & we got a Defeat.
My point is, I don't care if you got a 1/16/4 KDA. As long as you stick to the team, we can win this. Don't get cocky-headed & provide kills for the enemy team like it's nothing.
