I've already listed the garrison buildings that collectors will be interested in, but here are some other "to-do's".
This list is mainly to help myself organize and plan for collecting in WoD; hopefully it gives others some direction too. :)
Horde - Bone Wasp (Laughing Skull reputation)Note: I'm unsure if the Sha'tari Skyguard is the same thing as the Sha'tari Defense, a new unlockable faction via the Trading Post building in your garrison. This building unlocks a horde faction (Laughing Skull) that sells a pet, so it would only make sense if there was an alliance one as well. However, the Sha'tari Skyguard is currently a faction that can be accessed by both horde and alliance (on live servers), so it's confusing that the pet is listed in the Pet Journal as something from the "Skyguard" instead of the "Defense".
Frostwolf Pup (Frostwolf reputation)
Alliance - Draenei Micro Defender (Council of Exarchs reputation)
Sky Fry (?) (Sha'tari Skyguard reputation)
Archaeology - Ancient Nest Guardian, Frostwolf GhostpupI have the secondary professions (arch, cooking, fishing) all set and ready to go for WoD, but it looks like I'm going to need to level more toons and professions. Thankfully my toons with engineering and mining are already level capped and skill capped, so I'll just need to put some time into them in WoD. I'm still missing a tailor and blacksmith though, ugh. Perhaps I can convince my other half to dust off his alts to give me a helping hand? ;)
Tailoring - Elekk Plushie
Engineering - Lifelike Mechanical Frostboar, Mechanical Scorpid, Mechanical Axebeak, Sky-Bo
Cooking - Lil' Leftovers
Herbalism - Nightshade Sproutling
Mining - Ore Eater
Blacksmithing - Soul of the Forge
Fishing - Land Shark, Sea Calf
So much to do in the near future, ahhhh!
