Not sure if this has been ticking on in the developers' minds, but here is a suggestion for HM Thousand Maws of Toto-Rak:

The layout would be similar to 1.0's, not completely the same, but with a similar goal. There are three sections that players can travel to: The harder the path, the better the reward.

The first path was shortest (took 4 magitek power cells), which led to the easiest boss.

The second path was mid-length (took 8 power cells), that led to second easiest boss (two big scorpions).

The third and final path was the longest, but had the best rewards and the hardest boss (you had to open up the previous chests though to get up to four chests at Shaula).

Point being, I'd like something like that to return, where you're giving alternate paths in a dungeon.
