well i will tell you my suggestion:
armor: imperial armor (heavy xD)
weapon: duall angel slayer (and a draconic bow with you for UD)
Buffs: all your buffs exept blue (is for mage and you need mp)
welll now i will tell how i play with BD:
i do my buffs.when the match start and the oponent atackes me and my cp is 0 I go to the midle of the stadiumand use UD.. if the oponent go far we atack with dragonic bow (thats why we go to the midle.when UD finish we wear the dual angelslayer and start atack.IF our oponent start running (beackuse he has low hp and want to keep it)we wear dragonic bow and atack..
thats all..
don't forget to press left clicks at ss :P
i hope i helped you...
