Thanks for your indepth thought and time taken to type this up but I after reading I am still left puzzled. Why would bungie switch the ranking system (from Halo 2 to Halo 3) to this complicated mathematical calculations which probably only a very small minority of the Halo gaming community can understand, even IF they take the time to, from the previous more simple ranking system? Hindsight is 20/20; but, Shouldn't bungie have expected thousands of disgruntled Halo gamers? What were the motives behind bunige overhauling the ranking system and the game interface to Microsoft based/developed programs and calculations? Thanks.
