I can understand your PoV on this.
But FFXI had a completely different system for everything.
It was a game designed to have a much longer-life to content, and no-one complained about this. At that time people were happy to invest large amounts of time over a long-period to achieve a reward.
Leveling took AGES. Traveling too ages. Dying or failing had a huge cost to time or money. Content arguably lasted a lot longer in general as a rule-of-thumb.
If you sit for 3-4 days you can get from 1-50 in FFXIV.
A week or two at most if you want to take it slowly.
It took the most part a YEAR for most people to get to the cap on launch in FFXI.
It took considerably longer to travel from A > B.
Dying, failing content or forgetting to talk to an NPC could cost you valuable game-time, a detriment you don't have in FFXIV.
The majority of people playing FFXIV:ARR wouldn't accept the time-scale it took to do things in FFXI, there's enough market-data to drown an elephant to back this up. It sadly doesn't appeal to the many FFXI players (Me included) but it's something we have to deal with. Players simply don't have the time, or don't want to spend the time that they did before on an MMO. Especially when offer games reward players much faster with less effort.
FFXIV:ARR didn't want to have to have large time barriers between levels and new content, or have any detriment that would 'annoy' players.
Giving players the ability to play for a short-time each day and still get to the same eventual stage as the rest of the players over time is exactly what Square Enix want.
"But if they don't like it they can play something else then!?
No. This game primarily is here to make money.
Final Fantasy is at the end of the day here to make money. The other arguable details are important, but the product HAS to make money. And the data proves that FFXI-2 currently wouldn't make as much money as what we have now.
You're not being serious, right?
We're considering from ARR's launch.
The development time-scale between 1.0 > 1.23 just simply doesn't count (as no new content was produced for it on a steady basis, except for the few odds and ends to keep players happy).
All their effort went into producing ARR in 2 years and 8 months. To completely rebuild an MMO from scratch in that time with the amount of content that it had was nothing short of amazing.
MMO developments normally take 4-5 years, even with the small foundation ARR had to work-from that's an amazingly condensed time-scale.
So yes, it's completely understandable why we're getting content in batches, and even the content we're getting is coming out rather fast. It just doesn't last long enough if the problem.
