Why is it so common to join extremes without watching a guide first?

[Iyrnthota]

Ive personally never experienced anyone like that so I can't comment on it. I usually just get silent groups outside of like myself and one or two other people trying to help keep things organized. Is this a common thing people experience or is this one bad experience by OP being turned into a bigger deal?

While I haven't experienced it myself, I've seen enough people talk about it to know that it is common when doing Mentor roulettes.
Often sprouts will join EX duties using Duty finder instead of PF, which comes with a whole range of issues.

Some are not very polite when people attempt to explain the way things are usually done.
