Dark Forest - How far beyond the witch have you gone?

[dewey]

I've done wave 12 and the super ogres are starting to get pretty nasty. I'm curious how far others have gone though and is it worth pushing for random gear?

[Sir Ventius]

wave 19
you basically only see ogres with throwing stars and leather tunic and they do not drop anything special.

[Mr. Beartato]

I've gone to wave 30 or so. Yeah, it's just ogres forever at that point, completely pointless to do. I was hoping there'd be something else (hoping for a Witch rematch for her drop) but no.
