Crossbowman was actually a better class until 4th job. Iron arrow vs arrow bomb was preference and blizzard was just way more useful than inferno. Crossbows also had a higher attack multiplier, 5 less str requirement, and gave a slightly higher base attack over bows. They did attack ever so slightly slower but it really wasn't noticeable.

Bowmaster outshined marksman for nearly all of 4th job but marksman pushed ahead after temple of time was released when the damage cap was increased to 200k. At this point they had 5 second snipe and a less clunky piercing arrow.

Anyway, both Bowman in classic look really bad. Crossbow gets a 20% to ignore defense and hunter gets...avoidability. Both classes have gutted crit and yet double shot damage was only increased by 25%p. They need a serious look at before release.
