Dungeons: Make them less linear! FFXIV:ARR doesn't have to be a themepark!

[Gormogon]

I remember Toto-rak was like that in 1.0. Depending on which door of three you picked you'd get a different boss, though people only ever did the third and hardest to get to door to maximize reward payout. It was a great way to farm seals when you got tired of running caravans. Sadly, if they did add paths to the dungeons you'd still have people just going the route of max reward invalidating the paths in the process.

That can be solved easily.

Any direction gives the same reward. Yet 1 of the 2 rewards will have a slightly higher drop rate.

Example
Boss on left route: Chest 1 has a higher drop rate for tank gear
Boss on the middle: balanced
Boss on the right: Chest 2 has a high drop rate for healers

That doesn't have to be the only route.

Such as additions to hidden rooms with boss fights where chests have drop rates that favor a roles or specific classes/jobs. This simply extends the time spent on the dungeon but it is worthwhile.
Have mini-bosses spread out that buff you or debuff the final boss.

There's a lot of diversity to be had here. Question is the limit of the teams creativity.
