I've used 1-5 as a low level TTK (nothing past 3-2 unlocked) to level subs up to the point where they start being useful for Orel.

Because subs can't hurt each other, no one gets damaged and fights barely take any time at all. The battles result in 315 flag exp, rank D failures, but the battles are quick and efficient and if you have enough victories banked, the amount it takes to get a sub up to level 10-20 is easily absorbed. If you only run with one sub, she will come out sparkling as well.
