Drop Rates In Runescape - Is It Just Me Or?

I have never had a drop any bigger than around 250k, considering I have 75 slayer, that's not very good at all. Killed hundreds and hundreds or metal dragons, still waiting for at least D legs or skirt, but nothing. There's definately something wrong with the drop rate, and I like your theory about Effigies taking over the mains, it should be a drop with the mains, kind of like a clue scroll.

But it's kind of weird, I checked one of my friends Adventurer's Log's not long ago and noticed that in one task he received D legs and a D skirt off metal dragons, I was quite annoyed tbh LOL. Maybe we're just unlucky
