If the only way to progress or have fun in the game is to join a LS, or if joining a LS is required in order to have fun or talk to people, then the game has failed....
First and foremost, I never said anything nearly related to "the only way to progress or have fun in the game is to join a LS" or that joining an LS is "required". **** naw son, some people enjoy playing solo and just solo grinding over and over w/ no social interaction at all.........dot...dot....dot..... but hey if that's your cup of tea you can certainly progress and again if you like that, then it would be fun!
If that's the case, well... enjoy that, but why would you ever play a MMO (Massively MUTLIPLAYER Online - incase you didn't know)? Why play in a game that's direct purpose is supposed to be multiplayer and interaction with others? Sure there are methods to progress through solo efforts, because let's face it you can't always find a party (see FFXI looking for parties for hours) but that doesn't mean the game is a failure.
SE can't force people to chat to strangers in game, but that doesn't mean it NEVER happens... yesterday I was watching some TV and grinding a few crafting levels (completely ignoring LS chat) and I hit a rank up and gained a new skill. Four different people told me "Congratulations" of some sort, CG on XXX skill... congrats!.... good job!...
Also for side info, this Anpippin kid asks some really really dumb questsions, so it's possible people don't want to waste time telling him answers because he's too lazy to do any figuring out on his own. "I found a treasure chest, has this happened to anyone else?" (Nope.......... you're the only one!!!!!!!! OMFGG HAXX). "How do I get to Western La La from Camp Bent Branch?" (Really... look it up seriously).
The thread discussing how nobody talks is nearing its second page; the irony, it burns! D:
