Man.. I just had a perfect example of how attitude effects your rank. More than skill, strategy, mechanics etc.. your attitude determines how you and your team perform.
I'm on a 7 or 8 game winning streak in ranked, nasus being one of my main junglers, winning 75% of the time with a 6.5 - 1 KDA on him. My duo partner isnt on so I'm just doing normals. We get in, I take nasus jungle since we have little CC and no tanky people. I suggest we should invade at 1:50, as it's worked practically every time when I do it in ranked, hiding in the bottom bush from mid. I ping to tell them to go through mid into the bush, in case someone is staying in the river bush watching then they can't see us come in. What does our vlad do? Goes through river into the small bush. If anyone is in the other one, they see him do that and figure something is up.
Then, at 1:50 we move up and don't find anyone at blue. We take blue, but then 3 of them come up from bottom lane to ambush as everyone is leaving their blue area, Vlad had recalled already, and mid laner went the other way to lane, we're split up and outnumbered running out so we give up first blood. Vlad continues to bitch and moan about how that invade was stupid when he's the one that fucked up the most and likely tipped them off in the first place. Literally, he can't stop bitching everytime someone dies for first 5 minutes, even when they trade 1 for 1 or 2 for 1 and it ends up being 5-5 after 5 minutes and we had secured 3 of the 4 initial buff mobs on map as well setting the enemy jungler back.
He especially bitches at me for not ganking for him since he's losing his lane to a TF, or he pings after he engages TF but they both get away at 5% health, when I'm at bottom of map about to gank for bot lane. Saying it was a 'free kill' but he hadn't paid attention to the fact river was warded, which I had.
Anyways, he finally shuts up for a few minutes, even though our ADC (vayne) probably rage quit and it's 4v5. What happens? We actually start winning 4v5. But, then a tower falls top lane when TF is left alone to split push and starts bitching again. We IMMEDIATELY start losing again..
There was a bunch of other details that make it even more ironic/hilarious in retrospect, but if there is ONE word of advice I can give anyone trying to improve.. DO NOT RAGE. EVER! I don't care if one guy is 0/12/0 and you think he's the worst player you've ever seen. Bitching at someone has NEVER made them play better. If your goal is to the win your games, you can not rage at your own teammates, ever. Period.
Yes, you will still lose some games because your teammates fucked up, shit happens. But, for all you know, the person he laned against is a smurf and you wouldn't have done any better. Telling someone they suck or picking out how they messed up only makes them second guess themselves and play worse from then on. You would have a better chance of winning if you started walking up mid and committing suicide every time you spawn then you would bitching at your teammate for messing up. When I'm in a good mood, my winning percentage is at least double from when I'm in a bad mood.
