Every game has that same definition of ´hard´ for certain things.
But in this case, I just made a DK on a brazil server and got my minfirnal about the 5th time I checked. I only had one other DK, so it wasn´t annoying having to do the DK starter area again. The DK also helped me pick up a couple other slightly rare battle pets. I did see other players who had the same idea, but it was nothing compared to camping minfernal on a US server.
The devs are right though, these things are only special because they are hard to get. I have like 450 pets right now, could care less about 440 of them. I am not special because I have minfernal (no snowflake thing here).. but if they made it easier to get, it would just be one of the 440 others and forgetable.
