You hear often that the only difference between bind and assign is that it saves you that extra click.
Not so 
The “Assign” actually creates an event with the correct signature for that event dispatcher. Apparently in older versions of Unreal you had to set up a signature for the event dispatcher yourself when you create the custom event for it. You dont have to do that anymore Unreal does that for you in the latest versions of the engine. So the “assign” is just old. Depreciated basically. You can still use it though. So that’s the difference between “bind” and “assign”.
