You won’t get 1500 glory in the first example as they wiped your base. What I’m trying to balance is at what point within the range of results where you get maximum glory (that is, attacker:defender ratio from 2:1 to 10:1) do you also maximise troop revive rate.
From the discussions above, that looks to be as close to 2:1 as possible. For attacking, that means something like using 2/3 dragons to clear 100%. For defending that means allowing attacker to kill ~50-60% of your base.
