I just do 25 or 30 minute survival runs on any corpus map that spawns unlimited enemies (survival, spy missions) and I use mag. With shield polarize and a greater focus lens equipped, she was pulling 50k focus per 30 minute run. I also tried with Nova but she kills a bit slower since you have to wait until Mprime fans out and primes enemies. Mag just has to have 100% strength and max range and she kills corpus as soon as they spawn, even in other rooms. So in the time I takes one Mprime to fan out to enough enemies I can spam shield polarize 4 or more times.

Ember can be decent against infested but for higher level enemies world on fire doesn't kill fast. It stuns heavies for about 5 or so seconds before killing it. Again this is why I prefer mag because enemy level don't matter, it all dies in one second so as long as the target has shields on it equal to or higher than it's health. So oxium ospreys and sappers don't die from shield polarize becuase they either have no shields or have too little to kill them.

Stealth works too but recent hotfix nerfed the chance to get the 500% affinity bonus from steatlh kills, so while you can still get better focus xp from stealth than normal game play, it no longer competes with a lens on a AOE DPS frame becuase stealth bonus either gets reset or enemies go on alert after a ally dies from a stealth kill. So no 500% affinity bonus on every stealth kill anymore.
