Good missions to farm elites for mods in Agna Desert?

[Stormy Kami]

Iron Defense is driving me up the wall. Does anyone know any good missions on normal to farm yellow bars? This mod is haunting my dreams.

Commanding ground mission in the mirage area of Agna desert has 3 yellow bar elites that spawn relatively quickly.

Ran it to farm some positive ion particles for crafting.

I gave up for now an opted for spear and shield which I literally got immediately after I gave up on iron defense XD.

But thank you I'll try that one out when I do eventually try to unlock everything or need to elite farm agna again.
