Still not working for me on Whisperwind server. it wasn't working on warcraftpets.com either, but it worked there today. using another character on Whisperwind doesn't work. It does work if i use another server and character on this site.
If I try to use Magpie, it keeps trying to use the original character and server even though I have added the other character and server.
Update: Magpie worked this time when i entered the alternate character/server info. i don't know if the auction house is showing different information. I don't have any gold on that server to buy anything anyway.
PvP is something more than just choosing some pets. :) You play against other people after all, who are not predictable tamers, although one may try! Still, there are pets that are viable for PvP more than the others, and efforts to describe them have already been partaken. I can share you a link if you wish to – I don't say "no" in regards to the future of Xu-Fu's, but our squad… has no brawlers yet! :D
It does make sense that you would have to use the matchmaking tool but I don't see why this stops a list of pets being created, no matter how you get the achievement its still correct to state that there are some magic pets (for example) that are significantly better than others in any given scenario still exists.
I fully understand that in a pvp scenario you cannot state that following step A,B & C will win you that fight cause the data is not static.
You can however state, in absolutely no scenario would you use pet X cause it just sucks. Use pet F instead.
