Many ticket systems are awful for reasons other than being ticket systems.
For instance there are all the JIRA installations that have more options to make a ticket than there are dials at the flight engineer's station on a 747 in the 1970s. There are the issue trackers that run on a server that has too little RAM so it takes 30 seconds to load that bloated "create ticket" page.
I think making something more fluent than the typical issue tracker but more structured than slack would be the way to go.
