I commend 343 for giving us detailed patch notes and pushing the envelope to get the patch out earlier than expected (Friday). As a hardcore fan of Halo, specifically Halo CE and Halo 2, my passion comes from the ranking system. The pure competitive gold bliss that stems from match after match. The joy of ranking up after continued success in winning matches, then the frustration of losing matches and witnessing my rank go down, yet it only drives me to want to bounce back and improve myself and ultimately strive for the highest possible rank I can get it.
No other game quite does this, specifically shooters. Starcraft II is the closest game that gives that same sense of competitive bliss and offers divisions/leagues where you can improve yourself and literally see your ranking increase as a result.
Most shooters tie-in some artificial career ranking, which is nothing more than a World of Warcraft leveling concept, grind and grind away, while your numerical jpeg increases...never to decrease, in otherwords, it's just cosmetic to give you a psychological feeling you're good.
In ranked Halo 2, it's quite different. If you're a 10 after 100 games, then you know your skill level. While there's no shame being a specific ranking, for those who enjoy the ranking system, it offers fullfillment in competing online in one of the greatest console FPS games of all time.
Here's to hoping this patch will bring back the glory days of Halo 2 ranked matchmaking. I for one can't wait to dive in.
