The only problem with edimmus is they are task only. The pet is rare but if you could kill them out of tasks it wouldn't be as bad.
Rune dragons on the other hand are 5 1/2000 drops from an hourly spawn. That's like 10k hours of killing them. I've been playing this game for over a decade and I'm not even at 3 times that much time played. And I still play way too much.
You could make scrolls 10 times as common and they would still take more time than most things in this game. They're just ridiculous.
