I have personally been camping Sambas since I hit 85 on my hunter. I flew to his spawn point near the Krazzworks when a warlock links that Tear of Loyalty and says "WTS" . When I asked him who he got it off of he said, and I quote, a "random lion." I asked him if he was joking and he replied "about what lolol" and I said "Finding that lion." He goes "no i really found him" and I said "Why would you kill him... ><" to which he replies "was i not supposed to? he was rare lolol" . Of course, he was banging his head against the wall when I said I'd been advertising a reward of 500-1000g for Sambas location' and/or group invites/tags and all he was left with was a 25g tear of loyalty.
I wish Blizzard would get rid of the achievements to kill rare spawns as well as the loot that rare spawns may drop so hunters camping those rares won't have to worry (as much) about players killing their spawns "just because they're rare."
What's your best "my rare spawn was killed for loot" story?
