"Ten dollar words" 

I've always heard that we should never use ten dollar words when twenty-five cent ones will do nicely.  The sentence, "Many of those related disputes were ramified across schism boundries in polyphylictic fashion," is about as good of an example of "obfuscation by erudition" as I can cite.  I realize that this is about creating a reference work and that it shouldn't be written on a first grade-, or even a fifth grade-level, but this is too much IMO.  Can't we put this in a way that the more-or-less average Wikipedia reader can relate to and understand?
