Since my opinion is toxic

I will just point out that your sentence was actually being very contradictory, you are saying that putting people down is not the answer but you will likely drop and reject someone in order to win.
On a side not, why is it toxic to work on yourself and improve your skills when it's needed? The game is asking it for end-game, it's mandatory... So why it would be toxic to work on your dps/skill with the help of a parser in order to clear the hardest contents?
My opinion may be toxic, even though I stayed very polite... I'm sorry but I'm myself not a partisan of the "being a looser is the way to go", when I do mistakes or if something is wrong with my dps then I just work on it for the good of my team.
