That would still allow people to essentially buy to lot of gold which is an issue itself.
Gold buying is problematic, for sure.
I run my alts through gdkps each week, but don’t buy gold, and it’s basically impossible to actually land a big ticket item against gold buyers (I’ve seen some of them drop 30k+ over 2 weeks)… The flip side of that, is those morons are also the reason I haven’t had to actually farm gold myself in months, as even when I do win an odd piece of gear, I often still end up making gold for the run.
