Really impressive list Ampchan. Though I'm curious, : how did you get the dates for when we should have gotten these features? I've looked everywhere and couldn't find the date for when DMM got warehouse v2, so I'm surprised you got the dates for ALL these features.

Anyway, here's all the features I can think of that DMM has that we don't (However, I don't know when DMM had any of these implemented so I'm not sure if we should have them yet):
- Manyu Key Stages - These will likely be added soon though.
- Quest Completing Cumulatively - So you can clear one type of quest all in one go without needing to backtrack to the Quests page to claim rewards.
- Lvl 100 Manyu Forging - Can convert x3 Lvl20 Manyus into x1 Lvl100 Manyu.
- Ally Slots from early Campaign Missions - My Level 75 account on DMM has 59 slots and my Level 150 account on Nutaku has 37.
- Multiple Assistant Leaders - The Assistant Leader that's shown on your homescreen changes can be multiple girls of your choice.
