Lack of Incentive for old Add-ons

[Helldemon]

I don't really see why not, smn doesn't melee and bst very rarely does so on anything as well and they are the only job that would really benefit from master and pet buffs. People have been asking for buffs that affect both master and pet for years now though. What do you suggest then to allow more then one type of DD to be able to be in the same party and be able to contribute?
