What is your favorite place to slaughter hordes of enemies?

[Zebiko]

I typically liked low level survivals for endless killing of enemies and leveling gear. I pug all the time with randoms and they usually do what they want, running around. It wasn't a problem most of the time. I had plenty of mobs to kill where ever I was, grouped or not. But recently I been noticing the extreme lack of enemy spawns on survivals, like a few mobs a minute. It's extremely boring, sit there and just wait for them to slowly come to you. Going solo also sucks because that spawns less mobs than in groups. Idk if DE has changed spawning or what, but it's boring. I do notice that enemies seem to act more irregular now and weird pathing.

So, I ask, what is your favorite place to kill lots and lots of enemies?

Why survivals? Defense/mobile defense, excavations...

Sechura, Akkad, Hieracon, etc.

Survivals. I like the freedom to move around instead of defend a point/person, and I find after like 5-10m then they start spawning enough to fill up hallways shoulder to shoulder. Pretty fun cleaving through huge chunks of enemies like that.

Kuva Floods. They're so easy to solo, I find it hilarious to kill the Jesters. 

Reminds me of Maniacs only with better 'voice' effects.
