How many times do you help people.
All the time. I also end questions with question marks.

Katz is not right. There are plenty of stable groups out there. A few people may come and go, yes, but those people will regret it when the next new event comes along and they're like "take me back!" and the LS is like "no, screw you, you bailed when it no longer suited you to be here" but for the most part, there is always enough regular members to get something done.

My first endgame linkshell lasted for years. You can find a stable group if you know what to look for. And I still think it's silly to play an MMO and only ever play solo. Being able to solo is very important, but so is being able to be in a group setting.
