I can kill like 5 crog in 3 different spawns that i'm cycling. I got 19 Q3 horns after a long time. Since they don't drop gold, it's even worse. They drop plenty of q1 horns that i can turn into q2 horns, but in that case, we might as-well kill shroud knights. The most that they can give are leather and meat, but those are already super easy to get so i just trash them. I think they just need an increased rate on getting 4-5 q3 horns.
