In a game where part of their business model is releasing a couple of new guns every month I've used 90% of those weapons less than 3 times because they immediately feel bad at the highest difficulties.

100% this. The game went from making you feel like a disposable badass to just disposable bad. After a bunch of nerfs to the orbital weapons I just quit playing. I don't understand why they saw people having fun in record numbers and thought "something's wrong".
