You should learn how to post threads since You've posted 2 with the same subject and title. Same as in the second one all I have to say is : sorry but no. Stamina necro already have major defile in it's kit through stamina morph of blastbones. Adding minor would be complete overkill. Also I completly dont see how is it thematically important to add that debuff to siphon. Fact that it's disease dmg doesnt mean it should instantly give defile by deafault since disease dmg already have a chance to apply disease status effect which is major defile.
