Tonight i did main story R46 "Futures perfect".
As a mrd it was very hard. I died over 5 times before i succeded.
The key is that you need sleepmagic to sleep the mobs while a canon target them and kill them in one shoot.If you are nearby you will also get killed as the canon makes over 9000 damage in one shot.
With sleep its easy. Sleep mob, run away and baaam you are done.
Another thing i noticed is how fast my equipment durability was gone when i used return to revive myself.
Oy yes, forgot to told you about the great reward you get when finish this mission.
46.000 sp!!! and 138.000 Gil.
