Coffin Lid and wind up Echidna too rare?

[Jamillion]

I've run the Void Ark at least 30 times at this point (9 times yesterday alone), and I've yet to see the coffin drop. How rare can it be? I've seen rare minions drop far more often than this... This goes for the Wind Up Echidna too, have yet to see that.

Back in ST's heyday I ran it over 200 times and only saw two throne gems, that's just how raid drops are at first.
