They do seem to still be uncommon when learned, yes. Makes sense (despite the rarity), since they did say that all crafted pets should be uncommon now.
For those looking for this, it seems the rare spawn he drops from has a respawn timer of 50-90 minutes. I've had him be up when I come check slightly before 1 hour, and sometimes I've had to wait 30-40 additional minutes.
Just hope you have better luck than I do. Currently at ~50 kills and counting. O.O
