Ok, seriously people. THEY ARE JUST IRON SIGHTS. Not only do you have a choice in using them, but it's a really really trivial feature! I'd understand the rage if we were talking about something like a two weapon limit, but Iron Sights? It's as bad as those people who say the entire original star wars trilogy was ruined because they edited in greedo shooting first. It's stupid and trivial and I can't believe some people think it can actually make or break a game. Are we really this nitpicky?
