After getting 4 Madexx colors I decided it's the time to tame the last guy, green one. Sadly this one was the most troublesome and finally got him today after seeing Madexx at least 10-15 times in other various colors. Green one.. only twice. Once dead 2 days ago, and the one I tammed today. After seeing the dead one I felt really disappointed for not checking his spawn a few minutes earlier and decided to camp for a while.
Also including my latest solo Deth'tilac pic. Really fun tame and not hard when you are survival or just specced into "Entrampent" (4 sec root after getting caught in snake or ice trap).
And to finish my stables I also finally decided to tame Chromaggus today with help from my guildies

Now I am complete and full on stables slots :/ (including all 5 pets with me).
I could abandon Solix and brown/black Madexx, but I really hate doing that and the Madexx family seems happy as it is now. I just love that little scorpion guy!
At Deth im at 50% hp because I died once

Didn't have serpent on him/didn't attack enough before the tame and he had 12 stacks of Deth metal

other than that it's still not such a hard tame as some make it to be

I also helped rehome it once to an orc BM hunter who had trouble ressing his pet.
