Yeah all the endgame linkshells were watching Vtra on a 72 hour basis amiright guys?
Not everyone participated in the stuff you claim to be 100% of FFXI.
Assault, Besieged, Campaign, ENM, ZNM, BCNM, Dreamworld Dynamis, Limbus, Sea, Quests, Leveling, none of these overtly focuses on "Claiming your content" Stop with your hyperbole. XI had tons of content outside instances that was worth doing and hardly ever as competeted for as you make it out to be.
A few NM's being overcamped for marginally better gear? Sure it happened, we also had a amazing community from it to an extent. Not everything is going to be sunshine and rainbows even with all instanced content I can assure you that. Hell I bet when the next FF-online comes out there will be people like you bashing how XIV did things like people do with XI. It's an enigma wrapped in a puzzle layered over a conundrum how people have such selective minds when they want too.
I don't deny XI had it's share of issues and the 72 hour NM's were one of them but for the most part those utterly DISSAPEARED when they released new content, it's not SE's fault that people continue to obsess over content from the game during its early years.
The thing XI did was give you such a amazing expansion of option to do, with the level cap being 75 for so long the ammount of gear you could wear was astounding, just because some people obsessed over abjuration gear when there were hundreds of other viable options to them isn't SE's problem they weren't going to break game balance just to get people to come off of HNM's. Abysea did that, now it's all instanced and boring as hell.
Want to get anywhere in XI nowdays? Abysea runs!
This is the great thing about talking these issues out, because I have a vastly different idea than what you have about how the Dungeon finder can mess things up. I'm willing to support the devs and give it a shot when it comes out, but as it stands with the limited information we have available I am going to tell them why I think it's a bad idea.
A: It will be sucsesfull and playing on a server has absolutly no meaning anymore, economy will be either shot due to making dungeon loot rare/ex or flucuate insanely due to loot drops from cross server content mucking things up.
B: It will fail and SE will continue to push it because they spent alot of time/money on a system nobody wants to use, leaving people who want open world content in the dust.
It's hard to not imagine SE focusing heavily on instanced content with such a large endeavor to make cross server play possible and feasable. I think it's wasted time and effort I don't see many people screaming for darkhold or ifirit runs as it stands the entry requirement are nowhere near as harsh as XI was so finding a group of people on your own damn server hasn't been much of a challenge...why waste the time and money when it's not even a issue?
