Yeah, two or three more rifts would be nice. Even just the one at the rally point would be nice. There is that one statue behind that little voidwoken dragon that looks like it could become a waypoint.
I agree, at least two more rifts. One at the armory - but my preference is outside in the yard where the magisters are fighting, rather than inside, because by the time you could get access to the one inside, you probably are done with the armory, and a waypoint would not be so useful anymore. If the waypoint was outside, and only became activatable once the Gareth fight is over, then it could be more useful.
There must also be a second waypoint added in the east-northeast area, as it is too far from everywhere else and requires a lot of time spent trudging back and forth. The specific location doesn't matter as much, although there's a quiet place on a cliff's edge to the northeast of the camp which has nothing else of interest, it would be a fitting spot.
I wouldn't say no to one inside or just outside the necromancer tower after the maze, either, but it's a bit less important since that is pretty close to the seeker camp.
On a related note, it can be hard to remember which rift goes where to a degree. I don't think I made a mistake, but I always hesitated about which shrine went where. IMO, it'd be a lot better if the rift travel screen opened up the world map and you clicked on the swirlies instead of just a text list. Not a big deal, but would feel more polished and intuitive.
A map screen would also be helpful, as using names for the shrines is less than clear where they go. Braccus shrine, on an island full of Braccus statues. A Shrine to the Seven vs Lucian Shrine, etc...
