Doesn;t matter what it yields, when you can die and res in a matter of seconds it's not as low profit as you may think. Assuming you were to create a death macro that killed you and took a step toward let's say the luna healers. That might take 2 seconds at the very most if you do it right. That's nearly 50k bandages in 23 hours. Not a bad haul for free if you ask me. That's also 100k gold just to an npc healer. Sell them in bulk on a vendor and you can triple that I'm sure.
Let's not forget that anyone with knowledge of how to make a good macro could half the time and pull in around 90k bandages in that same 23 hours. All of that, just from dying and turning a death robe into 1 single bandage.
Ofcourse, as you say it is resource macroing. This is true, but some people are that stupid.
Sure it all sounds like small beans, but assume they were given a different value, to match that of a player crafted robe in earned cloth, where does that leave you? It really doesn't matter either way, someone will do it if that change is put in. Hell, who wouldn;t be happy to pull in a couple of million gold every 5 days just doing jack shit?
So, you say it isn;t much, but it's my job to see that even 1 bandage from 1 death robe is really alot more than it needs to be.
