"It's just normal"
Make this reportable.
I'm really tired of trying to do my best for the team failing because 1-2 ppl decided not to care and then reading this mantra because I either asked for help or suggested X to do Y.
I'm not trying to say that ppl should take normal as ranked, but at least try to pur some effort for the sakes of the other 4 ppl playing with you in a game where the objective is to win against the enemy team, no matter if ranked or normal. most of ppl using this phrase are just trying a cheap scapegoat instead of keeping a chill attitude while either saying "ok" or "sorry, I've messed up" or whatever similar. I do it, because I know that my fail will hinder my team. Another use ppl make of "it's just normal" and its variation is as a tool to make ppl tilt, using this passive aggressive attitude to try the patience of the other guy/gal making him/her prone to the use of not-so-chill replies which would be reported as flaming.
