Otacon Report: Karkin

Metal crab o doom
I'm not sure what hunter taming etiquette is. I'm definitely not up for causing more problems in a situation, but to be honest, I felt this guy had plenty of time.
The story
I was doing Molten Front dailies on Covington, when I saw him. Karkin, the metal crab. He was just chilling on a rock, waiting for someone to tame him. An undead hunter, who had begun climbing through the stones when I did, to begin two dailies in the Molten Front, tried taming him. I watched, but then realized Karkin's fireball attack is an AOE and backed off. I went about doing my dailies, getting thermostat readings and saving flight formed druids. I came back down and Karkin was still there. I took a deep breathe and forced myself to walk away, turning in my quests and returning to the front of Malfurion's Breach.

I tried resisting, but curiosity overcame the best of me, and I switched to Otacon. He was resting in a large cave, where Solix spawns, the orange lava spider I kind of want. I moved out and worked my way through The Furnace to Fireplume Peaks. There he was, STILL there; so was the undead hunter, but he wasn't moving. I poked him, but got no response. Conflicted, I decided to just go with it, and tried taming him. Well, it didn't work the first time. The undead hunter ended up dead because he was just chilling next to me, and was aoe'd fireball'd to death. I survived by Feigning Death, and took a moment to look up some strats from wowhead.
A simple, Tame, Silent Shot the lava aoe thing, Tame again worked like a charm. (The first time I autoshot, then Silent Shot, then Deterrence, then Tame, but it didn't work for some reason.)

I like his look in person then the screenshots I had seen previously. He also does these amusing animations, pointing in either direction and wiggling his lower jaw. It's too bad that he is a tenacity pet. I was hoping I could use him in PvP or PvE, but his special ability, Pinch, has a fairly long CD, and obviously, his damage wouldn't be that high compared to my Chimera or Ferocity pets. Still, an awesome addition to my collection. I still hope to eventually snag Skarr and Solix, but it seems like instead I'll have to settle for second best. XD

Hunter Etiquette?
The undead hunter who had been "trying" to get the Karkin, didn't say anything to me. He just mounted and hopped away. I was confused at what he was doing. Obviously he was trying to tame him at one point, but I was gone for a good 5-10 minutes before I wandered over on my hunter and looked to see what was going on. Not only that, but I wasn't the only hunter around. There was also a Night Elf hunter who seemed to just be watching the shenanigans.
I'm a pretty polite person. I watched Karkin get killed by an Alliance duo one night, but made it clear to the other hunters watching that I wasn't after it, I just wanted to see how to tame it (which was true). Another time, I even gave advice to a hunter trying to tame Bantha'los, but he just gave me very clipped responses or ignored me, and I watched him fail to capture him multiple times. I wonder if he ever did catch him.
I would whisper someone if I saw a rare I already had to try and get another hunter the tame. It's just nice.

So was it right of me to grab Karkin from the undead hunter? Honestly, he had his shot. I did not interrupt his tame and he even had a good amount of time before I meandered over on my hunter. I died twice getting over there.
But I might just be incredibly ignorant. 
So what do you think?
