What makes me frustrated is the spawns. It appears that most of the times, the governor has called out many more hunters than are needed to bring down the robots, except in a few places where it more comes to lack of equipment.
This is my experience so far:
Hadesheim C: At the time you have aimed at a robot to tag it, someone else has already tagged it and done at least 20% dmg.
Atlas Haven: Except for the first day, the only red dots I've seen there are the ones trapped in the basement of the tower. (I think the colonists would appreciate a way to get into the tower to kill them off
Fort Troy: Only green dots. Occasionally a red dot at end of radar.
Zychion: Nice for teams and probably ubers. But at my level most of the robots are too hard to take alone (eg warrior elite).
Wolverine: A lot of hunters around. It's huntable between 22:00-24:00 (and later) local time, before that it is what we usually would say "overhunted".
Nate Valley: From time to time nice spawn of (low-level) eviscs and (low-level) legionairs. Though, after have done a significant of damage to one of the mentioned and then getting killed by a Big Bulk that flies across the radar is frustrating (I get hit by about 80 dmg/sec by big bulks, so I could fap out one hit but not two fast hits in a row).
I try to do my share, but I know when I feel my time is used better doing other activities than stand in queue to bring down one of theese machines.
