I think its time for a poll on this..... I would create it but I'm "cutting back" on threads.
Not everyone will post their opinion about it(which is bad). As we saw in the server merge.
So, would someone like to create a poll?

here is my take on it:
Dungeon finders, they are great if you don't want to wait to make a party. That's cool and all, but... That will lead to always using it when possible. As I've seen/heard on these forums(I can throw out quotes) people don't want time syncs or give 30mins to just "wasting time". So, if this is implemented people will maybe shout once or twice, than hit up the finder. This is bad, especially for people like me that will boycott the system(as I am doing with the goobuu, I still don't have mine). If I get in a group that does that, I will leave(ya my choice I know).
So, I go about to create my own group. I get half the people, the people don't want to wait around for more people and leave(because I don't wanna use the system). I've seen it many times when I try and walk to places(they kick me). Now, that creates rude players if you ask me. If something is implemented for you to be lazy about something, you will throw that laziness at other people.
So, for the people saying"Just don't use it" well, it effects everyone, not just a few. Also, people will get away with other things, and maybe they will do that in their own community as well.
One of my many two cents about this issue.
