So many forget wall of fog really weakens arrows too and might even make DS not work on the professor or anyone in the fog anyway...

Oh well it's to be expected, not many play prof on here anyway ^_^
Trust me, DS is fine, it's one of the few ways archers have to kill players in pvp and woe easily, take out their capability to do dmg somehow someway and it's just like players with too much mdef against mages, it's really hard to win.
