@lafate actually, that's why I mentioned using gold buff + RtR, as well as occasional Deep Forest Road farming when there's not enough gold. if you're not actually leveling units to 50, but only to 30~40, it doesn't burn as much gold (estimated 100k gold per 40~50 level up using RtR farm). Also, I discharged all units obtained from Deep Forest Road. most of my starting units were also powerleveled to 50 using exp armor, so I made sure to reduce the gold I needed.

You do have a point with regards to farming DH (rank exp and gold saving, even if at the expense of unit leveling speed), but at least I wouldnt suggest using goddess buffs (7 SCs for that is a bit too much, I'd rather suggest using those 7 SCs to refill charisma to level units so they can actually pass castle retake)
