U didn't prove anything in regards to "I proved, he and many other pros do..." u said instances where one person has said something possibly toxic and mentioned multiple of those times with different people, none of those people are toxic characters who have consistently been toxic apart from maybe boostio and some of the old EG boys other than him, but the same argument can be made, It is clear it's all for show with those people, I could believe Ethan and Boostios rivalry could be real but once again that is them pushing each other and it will only lead to both getting better in the long run, once again I mentioned it doesn't matter to me who is being toxic, it matters to me fully how someone is being toxic.
there is a fundamental difference between Boostio and Ethans toxicity and N4rrates, N4rrate gets mad that people jiggle too much in a deathmatch where no one is watching, where whether he dies a few extra times to bs doesn't matter, if u ask any good pro for advice they would say "why tf do u care what other people are doing, just focus on yourself", n4rrate doesn't get that while Ethan and Boostio have a rivalry because they were teammates and now they both want to prove one another is better, there will be times where Ethan has had to sit down and tell himself that he's better than Boostio but he needs to prove it or no one will notice it, That is confidence, When he proves it then he has the right to talk shit, Narrate has achieved nothing yet notable in his career and to be as cocky and overconfident while having so many very noticable flaws shows how truly delusional he's being in regards to the truth.
"They know they're bad they just rely on individual plays" None of this statement is inherently toxicity, Toxicity is "abusive or disrespectful behaviour exhibited by players towards other players in online multiplayer games", you can argue it's disrespectful but considering Zellsis came out after they lost and said (paraphrasing) "yeah we played shit, we need to work on it", It's sadly just Leaf's read of Sentinels and it turned out to be the truth too, It's important to notice these small differences because how people act especially in their position is important.
