The way that I levele up my teams was very similar to  稻:

Focus on Tachi / Uchi team first, grind 4-4 until they reach at least lvl 50 then power through World 5 and keep grinding at 5-4. One go at 5-4 will earn your sword at least 3000-3600 EXP (without going to boss), they'll level up after around 4-5 runs.

For Tantou / Waki team, based on my experience, you'd better wait for an event to train them, will save a lot more time and resources than trying to grind them through Map 6, events will also give more EXP (Last WTE I ran my tantous team at E2 for 2 weeks and they moved from lvl20-ish to 70-ish with no almost no troops lost). After that you can keep leveling on Map 6.

Map7 is a longggg way to go so don't worry about that.

Kebiishi the map or not is entirely up to you, it won't be that bad if your team lvl are even and 5-4 is where most rares drop anyway, but will not be resource-friendly if you want to lvl up just one sword.
