http://en.wikipedia.org/wiki/Reliability_of_Wikipedia
I just read through article real quick, because I thought it would be fun. It is interesting that wiki comments on its own reliability, unless this article is also unreliable.
Now, just for shits and giggles, some guys random quote, and where you can find it, besides wikipedia (that is the best part about wikipedia, is, like any good secondary source, it cites the original source).
In his 2007 Guide to Military History on the Internet, Simon Fowler rated Wikipedia as "the best general resource" for military history research, and stated that "the results are largely accurate and generally free of bias."[44] When rating WP as the No. 1 military site he mentioned that "Wikipedia is often criticised for its inaccuracy and bias, but in my experience the military history articles are spot on."[45]

Anyway, read it yourselves, but I think I we are done talking about wikipedia as a source for now, and can move on to more legitimate concerns, which is why we need more then one team to being with. I believe that for balance sake, we should only have human teams. Obviously, if you want amazons, you can use their pieces, but why should they have a different stat line? I think asking for more then one team is crazy, and lazy, because people should just use their imaginations.
If you want a dwarf team, just take linesman, and play a few games, and have everyone earn block.
If you want elves, just make sure to roll a lot of 10 (for the extra agility).
Hell, with a little luck rolling 12s, you could have yourself an ogre team.
Its just that simple!
