My issue with ticketing systems is similar to most issues I have with this industry: cognitive dissonance.
On the one hand, companies ask me to put all this work into my tickets. Fill out this field, fill out that field, link to this thing, organize it this way... etc.
On the other hand, the company puts NEAR ZERO real effort into making this experience easy and efficient.
I've seen it happen most often with companies that flip-flop between defining themselves as a "start-up" but in the same breath talk about their worldwide enterprise presence. Of course they have 500+ employees. Sometimes thousands. They like to put on their startup hat when refusing to pay money for things and they like to put on their large scale enterprise hat when instituting ticket requirement policies.
