That's because you don't read Scarecrow comics. He has good stories that exist outside of fear gas spamming. Fear for Sale is a great story where Scarecrow does the complete opposite and removes Batman's fear (TNBA adapted it for "Nothing to Fear"). He does use his fear gas, but it's only to incapacitate Robin. Joker's Asylum is a fun story where Scarecrow gets treated like a horror slasher character, taking out a bunch of horny teenagers one-by-one. Again, he uses fear gas, but it's not the core of it. And of course, he's had plenty of other stories where he's used fear-related drugs, but not his fear gas.
The problem is people assume his gimmick is "fear gas". It's not. That's like saying Joker's gimmick is "laughing gas". Scarecrow's gimmick is fear, and fear gas is a tool he uses like Joker with laughing gas.
Another problem is people assume he's useless because all Batman needs to do is wear a gas mask and Scarecrow's useless, ignoring that Scarecrow can still point his attention towards innocents or anyone else. It doesn't always have to be Scarecrow directly dealing with Batman. He has stories where he attacks innocents instead, and Batman has to stop him. Or, during Underworld Unleashed where he instead attacked Hawkman and made him think he was being attacked, forcing him to attack innocents that he assumes are his opponents.
He clearly has the potential for good stories, and he's been used in good stories that don't focus on his fear gas and Batman. Writers just don't want to think creatively with him.
