1. Thorn DOT reduced from 7 to 3.
2. TLW damage reduced by around 30%. (Only some people are experiencing this.)
3. Pocket Infinity no longer empties the mag.
4. Reports of stability having a higher impact on stability than before. (Not confirmed.)
5. I've noticed drop rates are slightly better than before. Or it just seems like it. Got a bunch of blues and a legendary Engram drop right after patch and crucible is giving out more. This might just be luck. But it definitely feels different.
6. Materials on patrol seem more plentiful. (Speculation, not confirmed.)
7. Several icons for items have different colors/icons.
8. Ice Breakers perk acts like firefly now but for body shots too.
9. Various slight Graphical Improvements
10. Auto Rifles sound different.
11. Various UI improvements that are generally more informative. I am too lazy to list them all.
12. Weapons you pull out of the vault no longer show they have upgrades.
13. Connection status bars are now available.
14. Praetorian Foil perks changed from Javelin to Perfect Balance.
Feel free to post if you have discovered what you think is a buff or nerf so we can have a central place to list them.
