". . .the party members should be able. . ." meaning that is the system's design or what you would like to see?
Well, in 2.6.3 the party system was very bugged. In order to get everybody in the same instance, everybody had to be in the party, when the party leader jumped, everybody had to jump a few seconds after the party leader, most of the time you managed to get everybody in. This had to be verified in main chat. If some were not in, it was hard to get them afterwards in the same instance. After a while practicing it worked flawless. The most important part was good timing, get all noses in the right direction and communicate clearly.
You could try to join friends, but region mattered, you would start to load but didn't had any guarantee that you would get in the right instance.
Since 3.0 there has been a huge improvement in the party system. Partying up works the same, but when party leader jumps into an instance, everybody gets an invite to follow the party leader. No hassle anymore, either everybody reacts on time, or you can fall back on join-friends.
Now you can join friends, even at 49 of 50 this works, your region doesn't matter anymore, either you get in or you stay at crusader menu, no false instance loading anymore.
The huge disadvantage since 3.x is server stability and loading times. In 3.0 and 3.0.1 I could rely on loading times up to 180 seconds. Shorter was good, longer meant that I probably wouldn't get in. Since 3.1.x this time has drastically increased. 180 seconds is fast, 480 seconds is normal, but I also have seen loading times beyond 660 seconds.
I think marcsand2 once reported a balance over 1M aUEC?
That was hard earned money with ICC missions. Until 2.6 I hardly ever came in PU. Most of the time I spend my time in AC. Since 2.6 I started to participate in Combat Flight Training, multiplayer training. Players can give you enough work to get everybody in line, so if the universe is your playing ground and has no surprises anymore, you can concentrate on training.
Another factor was the time-span in which I earned the aUEC, the aUEC earned per mission and the aUEC spend per mission. Almost 1 year earning money, 5k per mission, only refueling and repair, no use of missiles or ballistics, fighting against all odds with a higher risk to die, all contributed to my positive balance.
