As i am new to MMO and in fact this is my first MMO ever i cant say if the LFG comments on the general chat are archaic or outdated.
But i can say that in my server which is Ahto City(EU) and in the republic side there are always people looking for groups to to HM,daylies even pvp toghether.
Yes i too do have a nice full schedule but from time to time that i entered to finish a quest,get some pvp action or something there where always people that where spamming general chat that they where looking for group.
Yes it would really be nice to have an automated system that makes balanced groups etc. but it may come ,it may not come.
As i said this is my experience,and as a new experience to me it's currently quite good.
