Where is the argument against staff increases?
If there are any trolls to be found, it's those that think just because they went back and skinned the old weapons, they can easily make some new ones. As folks like to do, I'll minimize the effort as best as possible: The trial weapon recipes are nothing more than copy / pasta, stick this effect somewhere. Coming up with new weapons that properly fit that theme is
not the same effort. You wanna hear a cliche? "Everything is so easy because tHeY hAvE mOnEy."

Nothing says you've never even set foot in a corporate or game dev environment quite like this.
That doesn't change the fact that MMO devs are constantly trying to move forward and avoid looking back at old things too much. It would be great if they could go back and fill in gaps, but there are clear priorities. If not getting a pretty design from 3 years ago is breaking your investment, perhaps you need to sort out your own priorities.
