Why in god's green Earth do dungeons have a timer?

[chocomaid]

Please explain to me why a timer is necessary for FFXIV when it is not necessary by a longshot in any other MMO I've played (including some pretty heavy hitters). And incidentally, your derision towards roleplayers doesn't actually make you a better person. You're playing an MMORPG; there is no high horse here.

Servers. Different data. Experience.

1. Those other MMO's might not have the traffic/popularity as FFXIV, so they don't need a timer since there is plenty room in their server. Forecast probably shows that traffic won't change in the foreseeable future.
2. Those other MMO's HAD PLENTY OF TIME to adapt to the traffic. For example WoW, were you there at launch? And even a couple of years in, there were queues in the log-in screen. And timers weren't a problem then since the ease of "duty finder, dungeon finder" wasn't implemented yet. You had to make your groups and actually find then go to each and every instance you needed to go to. That will automatically reduce the load on their instances since people won't just be mashing the "queue up" button while waiting, they'll have to work for it and it probably discouraged a lot of people going to faraway places for example.
3. Their servers are set-up differently, every game does.

Well, they are harming certain people's enjoyment of the game and are a symptom of poor planning. Yes, they are real problems.

You described yourself as a RPer, nothing wrong with that. I just don't see how a session can last more than 90-120 mins, and if it does go over that, why not just re-do the instance? Will it inconvenience you somehow, maybe. But guess what, it applies to both RPers and players that run the dungeon normally. There are solutions to your (vast minority) problems, and the rest are happy they are there to mitigate long queues and apply balances.
