Friend list has gone up about 10 people since launch day.
Fleet... Has ups and downs.
Adding this.... Know that 2 people have stopped playing but other than those 2 both fleet and friend list has been growing steadily... And have to reject all these random requests Chat get from complete strangers.
Recruited one new fleet member yesterday who came over from another MMO RPG to join us in STO. At the same time one from our Guild who tried STO Trial has left, so +-0.
As I mostly have my friends in the fleet my friendslist is the same with 2-3 others on friend. Keep Fleet members on friendslist so i can monitor from Buddy/Friendlist here on Forums from "My Account/Buddy List" if they are online. Can't see Fleet Roster from here, only friends.
Don't see the point with 200-300+ Fleet Members as that would turn fleet channel into Zone Chat. No way You can be on personal friend basis with 200-300+ Players. I like it personal if want pugs I use zone chat. No need for Fleet chat with pugs You dont know.
IMO the biggest reason that Fleets are a non-starter in STO is that there is no recognition of them. This is also one of the many reasons that the Nocti (Sidus Noctis, a multi-MMO gaming organization I belong to) has lost interest in this game. It does not say <Sidus Noctis> above our heads.
End result: Guilds, Clans, Legions, Factions, Fleets, etc. are immensely important in an MMO. Being a recognized member of them can sometimes be the driving force to making players log in to a game. This is especially true of a game that otherwise lacks content. At this, Cryptic fails.
