I really want all of the weapons, Attachments and gadgets to be unlocked in the training grounds. Basically, I want the class mastery to be unlocked only in the training grounds map, no other game modes should be affected as for balancing. I want every single weapon, gadget and attachment to be unlocked from the start and available for testing from any level. I feel that this will contribute greatly to the feeling of reward of the player, when they test something out in the training grounds and, when they unlock it, they would want to play with this weapon in the real game and see if it will be as cool to use as in the training scenarios. Also, it would make video creator's job way easier if they want to create "all weapons/reloads" type of videos.
