don't vent because of poor play teach them a proper rotation.

While I can agree with what you're saying, I understand and empathize with people's frustrations if they are in a Savage Farming party or in EX Roulette and there is no one new in the party, where they expect everyone to know what they are doing (especially in Savage).
I think it also needs to be pointed out that people need to also speak up if they are knew to content, there is usually one person in a group who is more then willing to explain fight mechanics.

I agree and is why discord can be a viable option. It is easy to talk to someone rather than text.
