On some maps, there are various rock formations and buildings that Bucket’s head just will not fly over.
Why is the UAV’s movement not entirely free, within the bounds of the map? It seems to be tied to the ground, or something weird. At certain times the UAV will not descend at all either.
All in all, not having completely free control is frustrating, breaks any immersion I had and is generally pretty poor for gameplay. If it’s for ‘UAV flying outside the map’ reasons (too high), surely it could just have a countdown timer, like when you’re a Hunter and you manage it (but shorter, i.e. ~3 seconds, to prevent abuse).
Essentially: Bucket’s altitude control should be just as free as its movement in the other two dimensions.
