My apologies if I am one of the people who made you feel this way. All the same, I disagree with many of your points. True, there are things about the game which I don't enjoy, but they're pretty much none of the things you have listed on the OP.
Customer service does not get final say on what is and is not implemented into the game. Most of your arguments on your OP relate to what does and does not get implemented in the game, which is not customer service's domain. Their domain is letting the devs know we're unhappy with it, then letting us know the devs decisions on the matters.
SE has a hard enough time keeping their customers happy without sinking a pretty penny into advertising. At this point, I think advertising would be a waste of money unless they update the graphics engine first.
This makes you a casual player, which is fine. I am glad that they have events in the game which can keep you satisfied with their duration and difficulty level.
I enjoy challenges like this being in the game. It gives me something to strive for. Neo Nyzul was an interesting one. It started with me and my friend shouting for 3 DDs (I dualboxed sch and cor). After a few really bad pick up members who couldn't follow instructions on when to hit their lamp, we decided to form a static. It took us a month worth of failures and eventually all of us getting on skype so we could communicate faster, but we finally started getting floor 100 wins. Once you start beating floor 100, it really doesn't take long to get all the gear you want.
What I'm really saying here is that ^that^ is what I love about FFXI. Being given a seemingly impossible situation, then finding a group of people I can slowly work it out with.
I know that might not be your cup of tea, but please don't have SE take that away from me. I'm not asking them to get rid of the events I don't enjoy because I know there's people like you out there who do enjoy them.
MMOs are always really rough in this sort of situation, FFXI being no exception. FFXI at least has the bonus that if you learn a different language, you might stand a chance, but that's not an option for many of us. When you get back to the states, you should consider giving it a try again. 14 bucks a month is still cheaper than most hobbies. Or maybe give FFXIV a try when it reboots. I think it'll be even more casual and fast-paced than FFXI.
Thank you for this post, it is a large improvement on the original. It is easier to understand what about the game frustrates you and why. I get the feeling SoA won't drag on as long as WotG did (I really do hope SE learned their lesson), so maybe you can return sooner than that.
