Your experience with database replication is not unique. I have seen
this happen with many flavours of database, not just MySQL. At the
"critical" sites where I've worked, database replication is not even on
the table as an option for precisely the reasons you state above: I have
yet to meet someone else who has had a positive experience with it.
