In all this days i just find 2 white mob umh not that better silver but drop ok seem 50% more!
And just today since the start i just find 1 Blue Mob killed him give me 1 level and 20% Exp from 149 i got 150 and 20% 
they should increase blue mobs xD
haha would be nice xD so we could power level somemore, but atleast we can enjoy the storyline, even tho the game is most likely made as a grinding game 
They should also increase the HP dramatically, nothing is more frustrating to know that you were one tenth of a second away from hitting one of them.
My first blue mob was a lvl 7 pokubu I guess… I earn 11k base exp + 8k job exp… jump from lvl 10 to lvl 15 and lvl 15 job…
Pretty neat
