Ghostring's default works in PvM by default.
The only reason that on Anthem it is "nerfed" is because you can buy cards--thats it.
On servers that follow default, you can only attain it at a low chance from the monster or an OCA. In a real server, you wouldn't be able to get a Deviling, Tirfing, and Ghostring together unless you spent months upon months of 24/7 Hunting--even then, somebody can get to it before you, and a huge huge percent of the time it won't drop.
Thus, the reward matchess the effort; in Anthem, all you need to do is buy it and it will make it a snap to get from 1/1 novice to trans even if that was your only character ever.
