Naughty Dog's Multiplayer Designer Justin Richmond got back to us with some answers:
Was player feedback the reason for the tweaks? Or was it internal?
A little of both. We LOVE getting feedback on the forums, and appreciate everybody taking the time to post about what they like and dislike. The data from the players themselves is invaluable.
Almost everything we patched for was stuff that was broken in code that we could address in a short amount of time. We did raise the score limits in the game pre-patch due to overwhelming player response. We have been looking at the forums constantly and are aware of all of the issues that people have with the game. Already, changes have been made based on feedback from the beta that are NOT in the patch however, and we will continue to do so as we hear from the players on the forums.
What specifically was changed about the grenades? Made more powerful? Less powerful? Can you still teamkill with them?
Players will still take team damage from grenades as they did before, but accidentally grenade killing your whole team in the first seconds of a game are being fixed for the full game. We are also tweaking the "kick" system.
