I actually agree with you in principle, people should team up and defeat NMs together, and it is true that you feel a better sense of accomplishment if you defeat a strong monster to get gear, than if you just click on a Gobby box. Also it is memories for the rest of your life, the time you and some friends pulled off a surprising win against a formidable foe, and you got a cool item you wanted. Those are indeed the greatest memories.
The Dev Team are working super-hard and pouring so much enthusiasm into their creative process, to try and make the game as much fun as possible for everyone. I can see this every time I visit this POL website, the Dev Team announcements are always filled with enthusiasm and hope, the Dev Team are doing everything they can think of to keep this game enticing for new and old players.
Having special login items, Gobby dials, and bonus events, this is the Dev team working very hard to try and make new and old players happy.
So a few years ago I put my principles on the shelf. Now I'm just so thankful every single day, FFXI is still online, I can still visit Vana'diel, still see my Tarutaru and my Automaton. I'm SO HAPPY that the game is still online.
And it is so obvious to me that the Dev Team love Vana'diel so much too, and they are trying very hard to add fun mini-events and novelty dials, and they've added so many improved game features, to add extra layers of fun and novelty to adventuring, for beginners and veterans alike.
