A feature when you can post you items for sale and search for specific items you are after. This would make trading much easier then hoping the right person sees you in world chat
This is a popular request, as far as I know. However, bigger games like Path of Exile have shunned a proper auction house under the belief that it encourages more botting/automated/“fake” players, which would undercut real players trying to compete in the market as sellers. May look up a statement later, if this post trends. I’m not against your idea, my comment is more something to be very cautious about.
You should be able to trade plates for the smaller folks to grow plus after HLBC,etc they just take us space smaller alts could use them extra one. Plus folks my size could trade for fast sands rai and deepmines I’m still small and growing at a slow rate
