Clear your story mode while leveling your units, aim the get your rarer units leveled. Black > Plat > Gold > Silver > Bronze > Iron
Focus on leveling your gold units and above.
If you haven't tried, do strat lesson quest and unlock katie, a core gold soldier most people use even into lv100-200+
Then try urgent mission drills and challenge quests. The initial challenges are pretty easy and help you use your stam bar.
Extra drops are given ONCE, if you clear a map. Dont waste your silver units by combining it. Save your silvers for "class evolution".
Overall, aigis is one of the more complex and interesting games in nutaku. You won't be disappointed if you keep going.
