Halo Reach Impressions

So, I dove into Halo Reach beta for the first time this past week. To say the least, I am very disappointed.

First, let me give you a brief breakdown of the changes that have been made since Halo 3:

Improvements:
-The matchmaking menu screen interface has been cleaned up and simplified.
-The graphics are very sharp and really pop.
-The game requires more skill than Halo 3 due to the fact that its main weapon, the DMR, forces you to employ precise aim to dispatch your online hostiles.
-The multiplayer levels are a HUGE upgrade over Halo 3's maps: while they are still intricate, the levels are much better organized (with a number of symmetrical regions) that make them easier to navigate and more enjoyable.

Downgrades:
-The weapons are not very well balanced -- some seem too powerful while others make me think that I would be better off picking up pebbles and throwing them in the vicinity of my opponents.
-Traditions that have existed in the Halo universe have been dismissed in Reach. For example, you lose health when you jump, and the melee attack feels different/removes a different amount of health (so that the pattern of shooting/meleeing that you've grown accustomed to may not work in Reach).
-You have a health bar and a shield. You have to run around the map finding (sparse) health packs to restore your depleted health.
-The armor loadouts are an unnecessary distraction. I would prefer the game to be much simpler, simply focusing on the weapon combat. Adding an extra layer adds more frustration and some of these loadouts slow the pace of the game down immensely (especially the loadout that provides a wounded player with a shield that makes him temporarily invincible).
-It's still Halo, meaning you will have plenty of "WTF?!?!!!" moments in regards to feeling that you got cheated by your opponents.

The last time I played the Beta was a week before it went offline. After getting screwed over royally by glitches and lag on numerous occasions, I angrily turned my Xbox off in the middle of the game, and refused to play it even once more before the beta period ended. Now, I understand that this is a beta, but, the game feels so cheap, so unpolished, that I'm angry with myself for reserving it (even though I cannot deny that I'm going to buy it simply because it's Halo). Hopefully Bungie will clean up the major issues with the game by the time it hits store shelves. As of now, I feel like I'm going to be getting more playing time out of Halo 3 than Reach...we shall see.

P.S. I believe that Halo 2 provided the best multiplayer suite of all three online Halo games...if Bungie released a game with Halo 2's engine and perfectly crafted multiplayer maps, I would be content. All of the so-called "upgrades" that Bungie throws into their games seem to merely water down the experience (I'm referring to power drains, regenerators, weapon loadouts...you get the picture). Bring back the simplicity of Halo 2, and cut all the extra fluff out of the package, and I will be happy.
