Imagine all unlocks were actually not in the game. Every class only has his 3 stock weapons. Any tweaks or whatever still apply but none of the unlocks are there. Considering this, what unlocks would you want to add (back) to the game, and for what reasons? Remember that this is not a blacklist. It's a whitelist - 0 unlocks are there and every addition must be justified. Not everyone has to write an essay, if good reasons for an unlock have already been mentioned you can just agree (or disagree) with those and then list some more you find important.
