FFXIV dungeons are a little bit too linear?

[Kotemon]

& what he said too --^

There's no point in making dungeons labyrinthine because people will always just find the shortest and fastest route to the end.

What he said.. ^

The fastest route is always a straight line. With people who just want it over with they'll speed run right to the closest or easiest boss> end it> repeat. If that old 1.0 dungeon ended if you fought Antares, that would be all the dungeon you needed.
Take XI, the only reason you had to explore places like Garliage, Sky, Sea, was either to find places to camp mobs for exp, hunt Nm's or look for quest/mission "?". Otherwise you had to randomly run about in groups hand mapping the place until you find that random mob dropping a key to a random chest in a different section of the area to get a dungeon map KI. All while drawing the shortest, straightest route to the various goals. Once Wiki gets the map and route/directions posted people followed that and avoided further exploration. Until I eventually got those maps I got lost so often in sky and sea. I just didn't want to go there past the main story or go further than the outside, and I still don't.

A timed dungeon that big from 1.0 would have a long queue line and have little room for mistakes. Imagine if dps was low, died several times to other bosses and you got to the end with 5 min left on a average 13 min fight; and one person wants to watch the 4 min cutscene. Keep it simple and keep it to point for efficiency. Otherwise a large multy path/segmented raid dungeon sounds good but if your held up by one group who is barely making it through, and decides to randomly loose 1/2 their members because the setup sucks. The other two parties on their own sections are now 'dead end" due to a lack of a third group. If anyone noticed, LoA, WoD, Void keeps all path splits in the same section and are not that far apart and can send 1or 2 from each over to fill the gap..
