Potential miss of sales (skins)

You guys are bringing out some really good skins / packs to the item shop but I hesitate and choose not to buy some of these $30+ AUD Packs because the skins are locked to a specific class. You haven't locked any weapons behind classes so why skins? If I want to run around in a "recon" skin as assault I don't see the issue or simply no one has to if they don't want too. But I just think you would miss out on alot of potential money/sales because of this. The Thanksgiving PAX pack is fire and I love the civilian tactical gear. But it's locked to specific classes unlike the NATO pack that just came out can use any character to any class.
