I got Halo Reach in late March and these are some things I don't think that Bungie should have put in Reach.
Fall Damage- Everyone gets shields so I don't understand why all of a sudden there's fall damage. In Halo 2, Halo 3 etc. there was no fall damage because everyone got shields which was basically your health. So the shield protected against any kind of fall damage.
Armor Lock- This is way too strong. I don't know how many times some guys uses armor lock and someone else will kill me because I am waiting on the guy with armor lock to get out of it. I think Bungie could have gotten away with armor lock just not lasting as long as it does when someone deploys it.
Size Change of Reticle- When firing some guns in Reach the reticle size gets bigger. Example: Sniper Rifle, DMR, **** Rifle, etc. I guess this makes the game more realistic. But it can make the DMR a pain to fire because you can't just rapidly fire it, you have to almost wait for the reticle to go down in size.
Detachable Turrets- This was first introduced in Halo 3. I like this idea for campaign and matchmaking. But when it comes to custom games at least give people the option if they want the turrets to be detachable or not. The reason I say this is because I loved to play tower of power back in the Halo 2 days. Since Bungie forged Ascension (Halo 2 version of Pinnacle) the least Bungie could have done was give the option of detachable turrets.
That is all. Opinions?
