If I do WoTG mission 26 and the sub quests, I get starlight medal or moonlight medal if i do the quest after.. Can I use those to buy medal rewards with Allied Notes like Rose Strap? Or do I have to do battles and go through evaluations for a medal.
Unless I'm mistaken, that just means that after completing that mission and its associated quests, your campaign rank can never fall below Starlight Medal. Pretty sure that you still have to go through the Battles/Quests -> Evaluation progression.
Doing the WotG mission/quest line only raises the floor to where you may be demoted to. If you're not up to that medal, you'll still have to get it 1st. But if you don't enough campgain in a 30 day period to get pormoted, you'll always just retain the medal up to the point where you are in WotG. Hoped that answered everything for you.
