lol DW was my main that i got it up to 225. He is not a "ridiculous mobber." Celestial Dance or not, Divide and Pierce suk major @ss as mobbing skill. The only merit is that you can one shot kill mobs pretty easily with it. Though PF update patch made the action delay slightly shorter and area slightly bigger, it still falls behind a lot of other jobs in terms of mobbing in 200s region (especially past 220). It can compete to be in midlow-mid in mobbing ranking if you can get one shot kill with 3rd job skill.
