Wraith Officer's Badge or WOB can be sold as 1k pieces stacks, since u need 8k in order to get 200k rep for r8.Taking in fact that 8k wob means 40 golds that is 1,2k ec, price is 1k-1,3k for 8k wob, that makes it 1k wob=150 ec.So, 100 wob = 15 ec
Stacks of 4k*
Most people just buy gold anyway nowadays...
