Hmm, I love pets, but when MoP made sooo many more available, they kinda lost me there...
releasing 300 plus pets has been fun, but I hope it's not the norm. There is soo many pets I have not even had a chance to summon them all yet. So while I do love my pets, I hope they plan to go back to the normal a few here and there.
I really hope they don't make pet battles far too hard. This is a fun little side game for wow, and shouldn't make me want to pull my hair out trying to play. So gemming or adding stats to mess with? Pass.
Keep it simple and fun. Don't over do the pets, let each one be special and unique. We do NOT need any more rat or maggot reskins to collect. Seriously, how many differnt names can you call the same pet?
As far as the battle stones, I think the drop rate is fine. We don't need epic stones, just give us a few epic pets and one legendary pet per expansion or something.
I would like to see more pet interactions with your toon and other pets. More unique interactive pet abilities. Bunny laying eggs, kewl. Skunk chasing cat, cute! But how bout a sea gull that can poop on your friends heads giving them a debuff for the day? Or a fowl mouth parrot that calls ppl names and taunts?
But yeah, don't mess with a good thing too much IMO.
