I'm sure the terrible players you're using to playing with have bigger and more obvious leaks, but I guarantee you that absolutely everybody playing 1/2 or 2/5 in your new room is beatable. It's just a matter of being better at plugging your own leaks and identifying and exploiting theirs than they are. And yeah, that means not playing exactly the way you did in the old room. But don't just change for the sake of changing. Identify what's different about their styles and adjust yours in whatever way is appropriate. For instance, if some players are capable of opening light frequently, 3bet them light sometimes. If they cbet often but rarely double barrel, float more often, etc. etc.
