The way I see it I'm fine with having to unlock certain items, unless there's a huge difference in the quality of the weapons that you start out with and the ones you get last.
For example, If the shotgun or rocket launcher was a weapon that could be unlocked and put into create-a-class then I wouldn't even buy the game. But if its like magnum, AR, BR, DMR, then I'm fine with it.
