It does get annoying hearing people rehash the same things over and over, but at the same time you have a choice on which threads and posts you read. The people at EA who visit this board have the same choice. I'm sure they're mature enough to realize what's helpful and what isn't. They should take comments like "the whole testing team should be canned" as motivation to do a better job testing the game next year. Some of the stuff that slips through (ex: some teams' schedules not being accurate) is inexcusable.
I'm not going to fault someone for venting their frustration unless it gets to a point where they're just blindly insulting people or something. If I get tired of reading their posts, I'll just skip them instead of complaining about people complaining.
