Yes Aigis gameplay in DMM is much faster and easier in DMM than Nutaku... I myself was able to clear Phalnax 2 within a month or so...
All it needs is...
2 cough*properly loved*cough CC Witches
1 mage CC. cough*loved*cough
Healer and Prince...
while it took me over 2 months to clear phalnax 2 on nutaku..
