This sentiment exactly. I have two modes when it comes to my impatience. Teacher mode- this is where I bottle up my annoyance and smile, politely inform people of suggestions or how to approach a situation. Or ask them if they want help, or if people who aren't speaking up need help in what to do. This is the mode when they are new players. It is easy to tell when you have so many years in these games, as you know. I love to teach new players, even if it can be frustrating at times. It feels incredibly rewarding to me to fail something badly, encourage and teach them what to do, and then watch them do it with ease without me even having to do 'extra' work. Everyone else is happy too. These are the fun times with sprouts; and a little bit of communication can go a long way in avoiding toxicity. A simple "If you're new, don't be shy, ask for help!" can mean the difference between someone silently struggling and a clean, easy run. I would much rather teach someone a single mechanic and clear the dungeon faster than start raging and bitc hing about how bad people are, only to make you waste more time by failing further. It is self-defeating and ignorant.
I have a second mode, however, and that is with clearly experienced players (the mentor stereotype, lol) who are being toxic. It is these people I have no patience for, because they should know better. Mentors that jump on the healer and tell them they're bad or need to heal more. Meanwhile, everyone is failing to do mechanics, that guy has been on the floor the whole fight. I recall specifically a mentor (while I had a crown on too) who berated me for not trying to raise anyone, when it was just me and one dps alive left. I was resetting, because resetting is the only thing we could do to not waste more time. The only reason people were dying was because some new players didn't know the mechanics, and there was no healing through that. He told the other (new, sprout) healer the same and told them to heal more.
I went off on him and asked if he was even paying attention, because no one had died from lack of healing, they were all dying from mechanics. That's me 'going off on someone'. I never call anyone anything or personally attack them. So many people do, and then complain they're being censored. You can make your complaints known without being offensive. It's not passive aggressive, it's just thoughtful criticism. There is a big difference, and the difference is your own confidence.
I have countless little stories of helping people. I have been toxic as everyone has, but every time I was, it only hurt everyone and made everything take longer.
I believe the phrase "don't worry about not doing well if you're new, as long as you're learning something" can mean a lot to new players, and I say it often. New players are anxious about being bad, but they're just learning, and it takes time.
