Add an endgame vehicle or offhand that lets you hover over all terrain.
For end game exploration it would be nice to have some kind of hovercraft or device to float over water, ground, and pits.
I can see this hovercraft being crafted or dropped from either Sahabar or Core commander so that it can’t be used before the endgame though an offhand that grants hovering would also be very useful as placing down a vehicle and tracking it’s location can be tricky for some players.
If a vehicle is the chosen route then I’d recommend giving it boat controls as opposed to car controls since boats are much easier to handle.
