If the game was properly QA tested prior to release this wouldn't be an issue.
Releasing patch notes to the community when the patch goes live is Basic Community Management. ALL of the other dev studios that have MP do it. DICE, Bungie, Treyarch, IW, hell even KAOS
If they don't release patch notes, tell me then, how exactly are we supposed to know if the patch is working as intended if we don't know the details?!?
IDK how many online games you play but this is how it works.
I'm part of the COD:HQ, bungie.net, infinityward.com, and gamesas.com (obviously) so I know how patches and details go. I also know that the devs don't have details posted RIGHT AFTER a patch goes live.
How many patches did IW submit within the lifetime of MW2? Maybe two? I also hardly ever saw any update details from them either and I used to be on their site religiously at work.
Sure Bungie has a weekly update, but most of the time it's just BSing around. Showing some videos, a lot of pictures, and an extremely vague explanation to what they MIGHT be working on, but they're about to quit that too.
