I saw many wanderer bads mocking and chiding our world players about them not being able to get into the zone. I see the same behaviors on some A rank hunt trains and S ranks and I imagine they are part of that group. Best just to keep to your own rather than be a rude visitor, we don't need you.
You don't judge one or two bad apples and call the entire tree rotten. You simply ask these foul individuals to mind their manners, and if they don't, there is a report system for that. Don't lose faith in humanity just because someone wrongs you, that makes you no better than the one afo wronged you when you treat everyone like that for suggesting an amiable solution and peace. :(
Congestion will be an issue even without wanderers once the progress bar fills. That's just the way of it, and instances will still be required. I just wish that such pessimism wasn't clouding an idea to help everyone.
than the one or two* who wronged you
I can't un-do whatever it is they said to you, and I'm sorry that it happened (because I had similar run-ins as I mentioned with prejudice from homeworlders), but I'm certainly not here looking for any confrontation, all I want is a solution. Because there will most likely be more steps, in which congestion will continue for us all.
I don't want to be crucified for the sins of another who wronged you is all. I wish that we could speak as equals without the sins of the father being the sins of the son.
