Service Desk Automation Rules - setting the assignee

[Claire Upham]

We have a group that is needing to automatically set assignees based on the statuses of one shared workflow. The assignees differ per customer request type. The current automation rules are configured per customer request type, but it doesn't always work correctly. In some cases, Jira will use the wrong automation rule to set the assignee, then correct itself. But the incorrect assignee still gets an email notification, of course. We have tried altering the JQL, but no luck.

I am thinking about changing the automation rules to be configured per status, and not request type. This way, Jira only has the read the automation rule per status and not have to check all the individual ones per request type. 

Anyone have any experience on this, or tips on best practices with automation rules in service desk?
