It's entirely your call, since they will keep losing troops in world 5 (even at higher levels 80+) but they will also ensure your scouting tends to be mostly successful. If you want to swap them out, tachi (or oodachi) would be a good replacement since their higher defence and attack make up for their low scouting stat.
