I do not think that it would be overkill for the alignment calculations, and I do not think that Keldaryths explanation about the system is simple. But using LaTeX to described the system would really make it nice and easy to understand.
Right now I cannot think of other places where we surely will need math, but then again we have not really consider many different game mechanics. If xapantu or andrew wants to give the install a try I bid it very welcome, but it is ultimately up to you guys.
Edit:
This might be the solution, it says it is easy to do, and does not require installation of LaTeX
The first section is the one, it should be easy to do
Also if we want to install LaTeX so we do not depend on other services, then we should probably ask Sourceforge about how they normally enable LaTeX math in Mediawiki (surely many other projects use it).
Edit^2: Probably a much more stable LaTeX rendering service is using
Google Chart, I think this is the easiest way to get stable LaTeX rendering
Edit^3: The
Google Chart option is very fast and very flexible
you can change the background and text color, and the background can have different levels of transparency
So a RGB 192 192 192 gray text color on a darkred RGBA 64 0 0 64 background would be this line
"http://chart.apis.google.com/chart?cht=tx&chf=bg,s,40000080&chco=C0C0C0&chl=\sum_{i=1}^n{\frac{1}{i}}"
And a normal RGB 0 0 0 black text color on a white RGBQ 255 255 255 255 would be this line
"http://chart.apis.google.com/chart?cht=tx&chf=bg,s,FFFFFFFF&chco=000000&chl=\sum_{i=1}^n{\frac{1}{i}}"
