As a late game carry if you're throwing a wobbly when you haven't died once in the laning phase and the team is ahead then you're doing something wrong.
There's a difference between correcting you and having a chip buddy. If I had a chip on my shoulder, I'd probably think about getting a new steam account/identity and worming my way into your games to abandon them and just ruin them for you. But hell, I'm not that petty.
I'm not gonna bother with the fancy red writing because I can't be bothered edit my post but hell, if you want to discuss it... let's do just that!
I think you missed my point. I didn't want you to heal the wave... it kills the creep waves and negates farm for the carry. The fact you weren't harassing to bully out the other MELEE offlane meant that you had to heal... which in turn meant that you had to steal creep kills, that the carry needed priority on. The fact you also didn't pull the wave when it got close to their tower--and you still remained insistent on your "hanging back and healing the wave" routine, meant you made it very hard to garner creep kills. Thus stopping the carry doing their job for the first 15-20 minutes of the game, haha.
Just to follow up on the other points, to further stress how little you get the point...
1. "At that level"? That actually means nothing. I play at that level, if I know to buy wards or whatever to counter PL... other people do as well. Don't be stupid.
2. I remember I never actually brought into question your ability to support, but I did get annoyed because by 20 minutes I wasn't where I needed to be on PL... Winning or not, it doesn't matter. If you're having a bad game because the person who was supposed to be supporting you is doing a poor job, you're going to get frustrated.
Doesn't matter if you've died 0 times, or 11 times. If the carry doesn't get farm and isn't ability to y'know... CARRY... it's frustrating. And your entire excuse for your bad supporting at the moment seems to be "It's fine, I play at such a bad MMR or whatever that you can get away with that".
Which would probably explain why you play at a bad level, constantly.
