The death of FFXI will be time. Previous to the announcement of 76+ we were suffering a stagnant, slow death. People had leveled all the jobs they had ever wanted up to 75 and were losing interest in end game events. They had all the gear they wanted, or almost all of the gear they wanted, and there was nothing enjoyable in the game anymore.
Abyssea is not the death of FFXI. It is a new, refreshing life.
What's wrong with wanting content in a video game? After eight years, you honestly expect us to continue being satisfied with the same, non-repeatable content? Currently the only way to repeat all of the content is to start a new character over and most people don't find that idea very attractive.
As long as we continue to pay for the game, we, the playerbase, want to enjoy the game. If there is nothing left to enjoy, we will become bored and begin to drift.
Besides, I'm sure it's a huge compliment to the dev team whenever we ask them for more content. That means we enjoy their work well enough to continue asking them for more.
Not true. As GreatGuardian has said, leeching is not a level, it's a failure to provide anything beneficial to the party. Jobs at 90 who fail to properly gear themselves are bigger leechers than the level 30s opening the chests.
And as someone who once had Bard 75, I can assure you that one, I would never want to be stuck playing it in Abyssea, and two, would not want to waste my cruor opening chests because nobody else wants to, and the alliance didn't want to get a level 30 to do it. If any party ever expects me to open chests as a level 90 who's actually doing their job, I just leave. I can kill fast enough to enjoy solo play and I think it'd be rude to expect anyone who's properly doing their job to give up their cruor for 17 other people. It's a trade off with level 30s though. They give us their cruor, we give them their levels.
