Yeah, I realise they're real easy with the N7 Paladin. The problem is that I only discovered the joys of tech bursts
after White got patched, lol.
For me, Dagger is the best place to farm Geth, if everyone
stays in the circular balcony and keeps their head on a swivel, as you've got great lines of fire to the two most common spawn locations, and can quickly reorient if they're coming at other angles.
...also, surprisingly, I have an Ultra Rare. The Volus Protector. Aka
BIOTIC GOD.
