Over the years I've seen many house rules here and other places on the web that seek to add more realism to the game. Although there are always areas that will make you question "Why the heck did GW do that", for the most part the SBG rules as of the One Ring/MoM rule set are really good. Not saying they are completely realistic
but rather they give a good feel for the skirmish-scale fights you see in the movies and they do it with a simple set of rules that are quick to play with minimal measurement and chart consultation. This lets you focus more on the actual PLAY ( enjoyment, tactical decisions, teasing your opponent, etc. ) and less on the mechanics.
If there's something that you and your local players are really bugged by (archery seems to be one area that is a hot button for various special rules) then by all means try to find something that makes the game for you all more fun. But in the process try not to get sucked into a downward spiral of making the game so "realistic" that it looses some of the fun.
IMHO
