I have a 4.0 or so. Good GDs spawn in Destard pens quite frequently and there are also other tricks and places kind tamers showed me, so pretty much no one needs a GD since they can go tame one themselves - or with a little help. There simply is little demand unless you meet a new tamer - who, this being Siege, probably doesn't have money to pay with, unless guilded - and then guildies would tame one for him.
