List of changes since the beta. I'm very happy to see these changes. Bungie is taking a lot of feedback from the community.
Faster movement, higher jump.
Game feels differant from Beta.
New Aim assist prioritises targets. Proximity doesn't always equal most valuable target
Headshot fix most import issue fixed from Beta - great improvement
Melee was "broken" in Beta, now fixed, longer delay (Five frames) (Melee in H3 is 30 frames) - so melee is now the same speed as Halo 3
Golden triangle, now "Golden Box" =P
Vehicles in internal Alpha "paper machete", vehicles changed from Beta, Sage currently working on them, no longer "fragile".
Getting Tank away from spawn in Boneyard was difficult, if you suceeded, Tank was powerful. Will be "improved upon"
Grenades - people initially perceived them as "mini-nukes" but then got used to them. Similar to CE. Frag power lowered by 1 point during Beta. Changed again, another 1 point taken away. Radius smaller, timer reduced by 0.1 second. One grenade will not impact health at all if no further damage is taken and shields recharge.
Shield wasn't reporting damage correctly during Beta - fixed.
Single DMR shot takes 25 points from shields
Maps and game types tweaked
Reticule fixed, brighter, fancier, quite noticeable, crisp, clear
Bloom stays
Where you are taking damage from is more visible - you'll know where the damage is coming from
Swordbase weapon spawns changed about - no Plasma Launcher on default! (right now =P)
Swordbase - Flag removed from Beta yellow lift room on 1 Flag (Battle over lift) - Flag moved to 2 story room with glassy balcony, top of the ramp. Plays better. Same on Powerhouse - Flag moved away duevto Rocket Launcher, on rooftop of one of the buildings.
Stockpile UI being redone, UI was carried over from Halo 3 - not suitable for Reach, confusing. Much more clear now. Stockpile
. Flag spawn locations kept the same. On Powerhouse "Stockpile" return zones moved.
Magnum slowed down fractionally to make it fair against AR users
AR is slightly buffed
Plasma Repeater kept in line with AR
Sniper Rifle made a bit more "idiot-proof"
Plasma Launcher "getting nerfed a hair" - "Clown Cannon, Comedy Gun". Changing time it takes to lock on to make it slightly more fair for infantry. Tracking also reduced slightly. Fire rate slightly longer/slower. "Not quite good as it used to be but still pretty awesome"
DMR - Rounds in magazine changed, 12 in Beta now increased to 15 rounds
Needle Rifle rounds in magazine changed, 16 in Beta now increased to 21 rounds
Magnum NOT getting more rounds for certain, no chance
Elite shield regen time increased from 3 seconds to 4 seconds (not final)
