This is my first topic on this site. I have been reading a lot, but now I found something worth sharing.
I bet this has been posted before, but here it goes.
When you are exalted with Ogri'la, you are able to purchase the tabard for 10 shards each. Each tabard is unique. So you purchase a tabard, and you can immediately sell the tabard back for 23 silver.
So it is basically buy tabard, sell it. Rinse and repeat.
Lets say you have a stack of 250 Apexis shards. Each tabard costs 10 shards. You get 25 tabards. 25 tabards x 23 silver = 575 silver, which is 5.75 gold.
the 5.75 gold you are getting may be just a tiny amount, but it is better than having stacks of shards using up bagspace for nothing, or better than throwing away the shards.
