Well Vesper in that context I totally agree. Common in the way it is used is very shaky at best when speaking of "realism", however the concept of common is a very real and necessary thing.
All cultures I think had one language at any given point in time that was considered the "common" or the "trade language" that way many different groups could function together.
Perhaps a way to use this version of "common" could be implemented. Giving humans their own natural language and having a second language called "trade" or something of the sort.
