(Carebears) have officially trumped Robots in my eyes as the cheapest and most annoying faction. I really can no longer stand playing them. The whole problem is space ninjas and goons.
Couldn't agree more. When I first started feeling that way, I thought I was going crazy, because Cerberus used to be the easiest faction, but these days... I might get more frustrated with Geth, but in the end, I probably have a higher success rate against them, even if achieving that success can be downright grueling.
I would say in general that the better balanced a given faction, the less a decent player needs specific kits or load-outs to deal with them. Geth are trivially easy with certain kits, but monumentally frustrating with others, and Cerberus is becoming like that as well. Several people have mentioned stasis users and stagger weapons, and they do make phantoms easier to deal with, but I shouldn't have to bring an Asari or a Scorpion to fight Cerberus effectively.
I feel like Reapers and Collectors, by contrast, are playable with any kit--yes, even casters and Vanguards against Collectors, though they tend to have it worst. At least for me personally, no matter what kit I'm using on UUG, if Reapers or Collectors comes up, I feel pretty confident. If Geth or Cerberus comes up, my reaction varies hugely based on what I'm playing.
