funky math (Score 1)

Does the wow team has a bit of a math problem? There seem to be some pretty basic mathamatical errors with WoW. 1. The first thing that comes to mind is the Seal of the crusader... i guess the question is how do REALLY basic errors like that get though QC? 2. There seem to be hundreds of items/enchants/buff/ that add up to a certian amount of x to y, or do a bonus of x percent to a skill or ability. Most of these don't appear to work all that well. Are there plans to fix these proublems, or at least make it clearer where damage bouses are coming from (like a verbouse mode for the combat log?).
