In the years since we moved over to Freshdesk, this hasn't become any less of any issue for us.
When merging 2 or more tickets, it is of no value to us for multiple tickets to still exist. The reason we merge tickets at all is so that only 1 ticket remains with all relevant data. It messes up our ticket numbers to have more than 1 ticket assigned to an agent, so we had to create a fake agent just to assign those left over merged tickets to.
This is really inconvenient, and honestly, I can't think of a single reason why we or anyone would want it to work the way it currently does.
