My guild just got this achievement on Monday and after I got the mount, I must say that I was very disappointed. This achievement is very difficult to obtain as well as very time consuming and requires a lot of effort from many other people to complete successfully. I feel the artists should put a little more time into their future conquerer rewards from Infernal Dawn and beyond and make their rewards more "unique" and stand out more, rather than just a quick copy and paste job and a color switch. The "Armored" is not even close to what I would consider armored to be, since 90% of its visible body is still not covered. Personally I think the Swift Armored Murdantix Bridle in its current form is a slap in the face.
Is this lack of effort on the mount purely because Trion knows that there is only going to be a small handful of people obtaining it?
