Beyond the pets we already know are a nightmare because of cross realm zones, here I am flying across western plaguelands just looking for 1 single pet i can battle to catch so i can finish my achieve, and every single one that pops up on my map disappears before my eyes due to crz. Pet battles are great, but the whole concept is going to waste because you cant find alot of pets due to this. I am dedicated, I will keep at this till I get it done, but there are lots of players who will run into this and because its glitchy from the crz abandon the whole thing. Really hope blizz addresses this issue in some means at some point.
