I am currently using Rain Caller, i am not in a raid guild, so might be a bit before i get my hands on a better raid quality bow.
Last night, by complete accident, i got this bow:

\aITEM -505207938 427673478:Bloodstained Bow of Piercing\/a
(136-409, 7.0 delay... cant seem to link pic)
my question is this: for raids, would it be worth adorning this (cant adorn Rain Caller) and using it? or is the Rain Caller proc itself more damage than the 10dps adorn i would put on this?
I am not rolling in the dough, so unless its a serious upgrade, i dont really want to spend the money on an adorn for this bow.
I am interested in raid information, not group/solo.
thanks.
