Obscure but good solo spots?

[Fregar]

WW brutes is a well known spot, but ya it's not as mainstream as some others.

I've never done it myself, but the iksar cave between swamp of no hope and trakanon teeth look like an interesting spot. (for lvl... 24ish??)
I don't know if they're spaced enough to be single pulled though, but I'd like to hear from someone who tried them.
