Other can get large depending on what apps you use.  It seems that programs like GoodReader stores much of its material there (I have many pdfs in GoodReader on my iPad, and simply removing them shrinks "other" by a many hundreds of MBs).  A lot of games cache data in other, locally stored email messages, the iOS notes app stores notes there, calendar events go into "other".  I'm not positive, but I think my Nook ereader app also tends to store books there, or its library sync data is there (and I have over 100 novels in my Nook library synced to my iOS devices).
So, it is not at all impossible for "other" to be several GBs in size with perfectly legitimate data in it.  Mine on both my iPhone 5 (32GB model) and iPad (64GB model) tends to sit at around 3%-5% of total storage.  But, as I say, I read and make notes on a large number of pdf, word, and excel files and powerpoint slide decks (although I always try to remember to convert those to pdf before loading them to my idevice), as well as use a couple of notebook apps for project management and meeting notes.
Some real-time geocaching apps supposedly also can add a lot to "other" as well.  So you may find that syncing does not reduce it, or even restoring as new, then adding back the apps you use and content for them, does not alter it much at all - I know on my devices with my apps and the kind things I use them for, I always have upwards of 3%-5% of total memory being used by "other".
