Who even dropped the hard-r at the lan?
The only person who I can imagine being mad at tagg's risky playstyle is b4nny, probably shade, but lansky, cyzer, shrugger? Really strange to hear "the relieve" of tagg's cut from them. He still did ultiduo with b4nny and was on the budsquad with cyzer, so I don't think that he stopped being friends with the whole squad like he said in the video.
But in general I feel for tagg, but as some people said above, gaming communities tend to host a lot of people with immature behavior, hate sparks built by rage, and people that communicate in a very rude and insensible manner, so you have to either deal with them or quit.
