lets cut the chit chat and face it
pvp is what has kept this game alive for ten years. it drives people to pvm so that they can find gear for pvp
trade forums get the most views, therefore its the location where threads such as 4v4gm/qq are more likely to be viewed
and the more pvp we have the longer trading d2 items is likely to continue
inb4 somebody says use legit dueling
legit dueling is filled with 1v1 ladders and practically nobody is in those forums, the threads they need are already in their tracked topics
if we posted in those forums, our duel games would never fill up
i haven't weighed in on all of the reasons, but its late and they can be brought up in discussion later
