I quite like the  presence of a dungeon timer. Ninety minutes is a generous amount of time and I'd rather not remain in a dungeon longer than that. It also has the benefit of encouraging a sense of urgency, since I've encountered far less players suddenly going AFK in FFXIV's dungeons than I have in MMO's such as WoW and GW2 that don't have a limit on the amount of time you can spend in a particular dungeon or raid.
Generally speaking if someone can't complete a dungeon in ninety minutes then they're either stuck with a poorly organised group or just need better gear. If I'm stuck with a group that doesn't seem capable of clearing some of the tougher dungeons then I cut my losses and take my leave, usually crafting a dungeon by hand with more experienced players.
I'm also not fond of the idea of making timed dungeons something tied to rewards and leader-boards. WoW did something similar during the latest expansion and it revolved around borderline exploits to skip most enemies through 'clever use of game mechanics' and thus the challenge was largely artificial.
