In business all products have a life cycle. My theory is that Social Linkshells (unless formed under unique circumstances) have the same.
Introduction
A shell is created by some friends and they use it to chat back and forth. Goofing around leveling core jobs maybe getting a few ranks one's and two's together. More than likely all are from the same nation.
Growth
Invites to the LS really take off and members begin to level their characters. People that are fun to be around and party with receive invites and they have friends that want to join so they get invited too. Killing the Dragon is fun and people are on all the time to chat and joke around. Cliques may start to form as a result of who helps who or what job levels are the same as people may be in a 'static' and not even know it. People in the LS really start to come together as a family to provide help and be there for each other.
Maturity
In the early parts of this stage people become separated by levels as those with the time have really leveled quickly whether its on adv. jobs or not. The players with the higher levels have had to find their own parties for various genkai and AF help. Once they reach an even higher level it is time for them to help players within the LS do their AF and genkais and they do.
Some recruiting continues but not as much, as most people they are now meeting are in LS's themselves and/or 'nubs' are not getting invited because they wouldn't share the same interest as the LS.
Decline
The 'Higher Levels' from before have reached upper 60's and low 70's to the point where they are attracted to HNMLS's. Mages go first and Melee second. They are between the two shells as long as they can but ultimately the time commitment and newfound gil keep them on the HNM shell longer than they can be in the Social shell. Soon they are doing activities in the HNM shell such as Zilarts/Gods.
The 'Lower Levels' are still making their way up but no longer find they have the 'Higher Levels' to help them. They inturn must now find AF or higher rank assistance on their own or with each other.
New leadership emerges as the old leadership is now doing sky farming/dynamis/gods/hnm's. The new leadership attempts to keep everyone happy but ultimately cannot as an exodus of most of the higher levels added to the fact that recruiting stopped sometime ago means that the numbers have dwindled. Players begin leaving in their 'cliques' dropping the shell altogether until one clique remains as the last remnants of what used to be a flourishing linkshell.
Has this been anyone elses experience?
I have played for a little over a year and watched this happen to my poor social LS. It used to be great fun full of great people. Often times 25+ were on sometimes 40+ on the weekends. Now as I and others have left to do 'End-Game' activites the poor social LS has ground to 1-2 groups of friends that still stay with it. Maybe 5-6 on at a time never anymore than 10.
Seeing the LS saddens me and while Kirin can be exhilarating sometimes I long for an impromptu marching up Delkfutts tower when we were all around level 40.
