Not "garbage" in the sense that if you were playing self-found, I imagine you'd get a lot of use out of them!
But you'd want at least +4 jav (+2 zon/+2 jav and spear/native +2 or +3)
I think 40 ias gets you more easily to your breakpoint without having to involve other gear, but it's been a while since I've played a jav zon.
The MAEK is really good though!
