May well be my bad RNG luck, but I've been killing this entire room every 16 minutes for 2 hours and I've seen the Murkglider Deathsting 4 times and the Murkglider Breeder 0 times.
I wonder if it is set to be slightly rarer with it being an epic mob? We currently have Feast of Giving on the server which is 50% increase on named. That may explain why the Deathsting is appearing so often, but the 50% increase may not be enough to make the Breeder spawn as often.
Just my 2cp.
EDIT, another 4 spawns and still no Breeder. Guess I'm going to need a sleeping bag and a cup of hot chocolate whilst I wait this one out.
