Ask a Bowman Thread.

Ah, I feel like my life culminated into answering this question.

I used my own Bowmaster with these equips. For the imaginary Marksman, I gave him a Neschere with 4 more attack than my Nisrock.

 Spoiler

Both characters are at level 162 (my level). I optimized their base STR, though. I lowered mine so that I could just barely wear a Nisrock without MW, and I lowered the Marksman's by 5 more for the Neschere. Of course, I raised their dex accordingly. Otherwise, I gave them both the same stats/equips. I used 2000 defense (Anego's real defense) for both sets of DPS.

The DPS for Bowmasters is easy. I calculated using 500 arrows a minute. The DPS for Marksmen was a little trickier. I took the average Strafe damage of my imaginary Marksman and had him do that 78 times and then added 6 Snipes (1 every 10 seconds for a minute) that average at 97000 damage (which is a number I was given my Marksman friend) to total 84 shots in a minute.

Bowmaster general stats:
4441 Minimum
5441 Maximum
160 Total Attack
973 Total DEX
110 Total STR

Marksman general stats:
4823 Minimum
5915 Maximum
164 Total Attack
979 Total DEX
104 Total STR

Bowmaster DPS: 74442
Marksman DPS: 62792

Hmmm Alex, if you're going to factor in snipe for marksmen, shouldnt you put in concentrate for us compared with say ciders or warrior elixirs? (Then again, we have Hurricane compared to their Pierce, which is really... nonfactorable into this xD)
