Gunslinger Build (Lv. 10-200)

Training method for gunslingers until lvl 70

What is best for gunslingers? I know they have the attacking speed of something faster double stab, not to mention they are ranged.

With a fast attacking speed and lower damage I would assume its best to train on high spawn, low hp monsters since lower hp monsters tend to have a better hp/exp ratio until you start hitting 1K HP and higher monsters. Not to mention higher lv/hp monsters would normally have a higher hp and def

So is it better to train on high HP monsters or fast spawn low hp until you get later into second job? Its like lets say you have a double shot that deals 100 total damage on average. Would it be better for you to train on pigs or start training on green mushrooms?

BUMP, and I have additional questions. IN LOWER LEVELS Since lower leveled monsters generally have better hp/exp ratio it is better to train on them until you over kill or 1 shot a monster that gives higher exp right?
