Can anyone explain me the use of dynamic_reconfigure?

From its description it says that it can change the parameters on the ROS parameter server during runtime without killing the node, but I can also do that myself using rosparam set <parameter_name> <parameter_value right?

What am I missing here?

Changing the property on the rosparam server does not mean your already running ros node will notice that the property has changed. The dynamic_reconfigure allows you do define a callback so your node will be quickly notified of the change (and possibly do something with the new value.)
