I am not even into xmog much, but I think this would be interesting and relatively low dev “cost” to implement. Make a show room at the xmogger and allow characters to take a photo in different poses in their mog. Make it weekly and players can vote on the best mog and give some kind of reward. Players could become renowned for it and could provide motivation for players to farm old raid gear as a sort of other progression system.
I know most will say “no spend dev time on making other content” which typically I would agree, but to me it seems they have all the systems in place already with some tweaking to do this. They could use the warband screen even. And then they could get into full warband xmogs. Seems like some low hanging fruit there.
Thoughts?
