Drops are dependent on degree, the game will drop more degree 2 items then any other degree in the game. The higher the degree the less and less drops you get. You are low lvl and get what 5 drops a full grind session? at cap(lvl 80) people can go a whole week with only one drop.

to gain exp/gold the best way is to kill a monster with one hit, since if you dont get hit you dont use hp and thus save gold there, and gold is dropped per mob so the faster you kill them the more gold you get, but be warned its usually just enough to cover the mp pots you just used.
