Just finished a game, I was Katarina mid. On the other team, there was Talon. I could say there was Talon and Shaco mid, really. Shaco was babysitting mid because I was hard pushing for 2 times. So I stopped pushing, yknow. The other times, they just went trought the turret and didn't bother at all about the turret. And the fun began ! The jungler and top started *****ing about me feeding and all. Shaco comes again, hit me, I run away. I stayed near the turret for farming. He went in our jungle and flashed invisible again for the third time in the same minute. Like he has no cooldown.. x_x Of course, I died. Again.
My jungler was still on my case (hard) about me feeding.. What could I had done? I have to say that our jungler never did help mid. Never ganked either. He was just b**tching and doing basicly nothing. But the game was still going on. Talon started roaming, shaco was doing his jungle job.. And we lose cause everyone of their team is fed. I was so pissed off..
I understand the frustration and honestly my bot lane was blaming me the jungler. Instead of raging back I asked them what they would like me to do to fix the problem. There reply was gank more. I explained to them where the wards were for the enemy team and when they had been placed. I then asked them 2 buy pink wards and ward clear and they did that twice and we made **** happen. I find the best solution when teammates are raging is to ask them what they would like you to change. Many times they will just rage more and then you just mute them before their negative attitude further impacts your game. Also many times when they dont have a viable suggestion you can insert what you need them to do better. We all have junglers that ignore lanes, dont gank, farm to much, or just gank poorly. You just have to focus on what you can do to make things happen.
The fact of the matter is we could not have won that game 4 v 5 but 5 v 5 we had 2 team fights that we won because of catching them separated and we kept a tight lock down on dragon and got all 5 dragons. I played the match all the way through because I was going to lose the ELO anyways (so might as well gain the experience of fighting an enemy from the losing side) and you never know when someones computer will randomly shutdown or a storm will take out their power causing a 4 v 4 or 4 v 5 in your favor. I know it is frustrating but like I mention above you are not going to win all of your matches and once you get over that you will win more games. Some teams will just not be able to win (due to a lack of teamwork) but unless it is 4 v 5 or a person is intentionally feeding the game outcome will never fall on one persons shoulders.
I hope this helps. Dont get down just keep focusing on your game play and where you can improve.
