Basically our need is,
When User X updates an issue, User X should not receive an e-mail
Our e-mail scheme is designed to be minimalist to avoid clutter. Therefore, we only send e-mails to the assignee and watchers when a change is made.
As assignee wants to know when someone else changes the issue.
However, they do not want to receive an e-mail when they update the issue.
For example, there is an issue JIRA-123.
I assign it to myself to resolve -> sends an e-mail Not needed
I work on the issue and update the description--> sends an e-mail Not needed
Our project manager adds some comments-->Sends an e-mail OK, I need to know
I resolve the issue-->sends an e-mail Not needed
