(Yet Another) Problem With League Players

There is a serious problem among league players. One of which is the fact none of them like the idea of new things. For example my last game my friend decided she wanted to legitimatley try Lucian jungle. Which yes its off meta and seems wierd but she was really going to try. But upon getting in game our other two teamates refused to help her because she was a "Troll". Still she kept trying to help them in lane, yet somehow she was always in the wrong. 0/1/4 at one point and she was called a useless feeder. Our Tahm Kench decided to just start eating her and throwing her at the enemy. Yet the enemy yelled at her and our tahm and singed blamed lucian. They would not let her explain and only continued to harass her for playing a off meta pick. After the game ended a few of the enemy team and our tahm and singed reported her. She wanted to play something different and legitimatley try and yet she couldnt even get past minions spawning before she was yelled at. This was all in a normal draft game. So tell me why is this okay? Riot encourages people to have fun. Yet the community will jump down anyones throat if they try something new unless youre a popular streamer. But if a popular youtuber or streamer tries it, everyone hops on the bandwagon... Phew sorry for my rant but this really really bothered me that she couldnt even get a chance to explain herself. It happens so often and its just irksome.

Anywho i hope you will give this a read and perhaps elaborate your thoughts as well. Id like to actually see peoples opinions whatever side that may be.
