Fascist's are supposed to be hated. You hate them now. Mission accomplished.
All joking to the side, Solo or not, level 40 to 50 is supposed to be where your mettle as a character is tested; its not about weather its a slow grind or not. You should be comfortable enough in your powers, how they work where the shortfalls are. You should be at least 1 respec in on the character, recalibrating when power and slots are picked; what worked and what didn't.
I have always enjoyed smashing them, before the change and after because I do seriously enjoy the concept of punching fascists in the face. They are a little harder sure, but not that hard, I run the content with Blasters and trollers. And while I see your attempt to compare revamping the group to 1-4 Star Difficulty changes as being slightly valid, its tiny little tangerines compared to giant assed naval oranges in truth. Non-Task/Strike Force/Trial content should be able to be completed solo, but that doesn't mean it has to be easy or stay static. The Arc where you have to fight Nosferatu is hard, and forced me to alter play style and use more temps, but that doesn't mean it should be tossed.
My fun may not be your fun but then again your fun may not be my fun. Adjust accordingly, that's what I do.
