SV having like five doubles battles total (and having them all part of the same gym) was disappointing. They even introduced a new pair of pokeymans whose whole gimmick was doubles, but they aren't in the doubles gym and their story fights were single battles as well.

I keep wishing you could swap between either singles or doubles as the default mode for the main game. If you keep it singles, every fight stays singles (except for certain gyms and pairs of trainers). If you elect for doubles, wild encounters will have an extra pokeyman show up and all trainers will throw out two of their pokemon at a time (again, except for gyms and trainers with only one pokemon). Let us experiment with doubles gimmicks in single player, dammit.
