To you fools talking about faction leaders on coins: what about the gold you get from killing bosses? I don't think C'thun has Thrall on his coins.
You are incorrect
How is it that each mob you kill drops cash and loot?
Easy, they are all on welfare
The tax on AH goes to pay welfare
The AH tax allows them the ability to buy the family some food and in some cases some luxury items
How does C'thun replace the items that keep getting stolen from him, easy the welfare payments allow him to restock for another week of raids
As such the gold coins are all minted
The Tuesday night shut down occurs because that is when the Welfare office opens and all the mobs and NPC's line up to get their welfare payment
And a horde character sending super leveling gear (boa) to an alliance new recruit (alt) can be considered treason, but you can do it.
I agree with your suggestion to cease the sending of BoA to the enemy
The BoA gear are actually Heirloom items
As such they pass down the line from father to son, from aunt to niece, or they are passed on through gifts to friends etc.
The opposing faction is the enemy and not related or friends and as such it make sense that Heirloom items cannot be gifted to the opposing faction
