So since I offered my help to one person once in a different thread and then multiple people contacted me because of that pet I decided to just open a new post to make this a little bit easier…
I can gladly invite everyone who still needs the Deathwatch Hatchling into a guild so they can get it. Of course you can also offer your guilds here should they have unlocked the pet 
Guild: Nephilim - Silvermoon
BattleTag: Shenk#2103 (just add me)
