i Dont understand why people think this party feature is great.
You need 5 people for example .
You put up party search for 2h and 2 other people join.In the end you could not find the 5 people you needed so those 2 h were wasted.

Now lets see the flag feature.
You do a sea and you see there are no 5 people looking for whatever you need. You go do something else.
Later 2h after you do a sea again.O hey now there are 5 people. you ask them to join and go hunt .
Really no1 see the difference ?
