this was always a huge arguement when wrath content mattered as i remember it. DBW is for purely PHYSICAL DPS classes ONLY Hunters, Rogues and Warriors and to some extent DKs. But if nobody wants it then by all means go for it if thats what you want but I would rather go for YOUR BIS trinkets instead due to the much better results you will receive.
To give you the extent about how Rets were never aloud to get one heres a story. (my orifinal guild) We are on DBS and it drops. The RL who was also the ML says roll for it. The only ret in the group rolls for it against the hunters, warriors (me and a bud), rogues and DK. the ret wins and all at the same time we say in vent he cant have it he does holy damage as his main source of dps and it is not his BIS trinket. The RL gives it to the ret and the Guild leader immediately guild kicks the RL. Needless to say the pally had to give it up to the guy who had the 2nd highest roll.
The guild leader let the guy back in to the guild. He kicked him to prove a point. You do not give loot to classes that it only half ass benefits before you give it to a class that will use 100% of it.
Once the removed ARP from the game though the restriction was lifted. (the guild I was in before patch 4.0) I remember that patch mostly cuz the AGI wrists that drop from that fight were BIS for warriors until they made non plate items and agility gear worthless for warriors with the patch. Those same leather wrists lead to an arguement with my guild vs my guild master about leather gear going to plate wearers because she didnt know about it those wrists being best in slot at the time and tried argueing that it should go to some druid who wanted to greed roll on it.
Wrath in general was a cluster F when it came to itemization and gear I am so glad it's over.
TL

R if no one argues then get it but keep in mind item level does not mean everything and stat allocation does.
