Not sure whether this will divide opinion or not but I personally feel all the FOTD cosmetic rewards (Jacket, face paint, lantern etc) should be time-limited and can only be unlocked this month. Obviously the Black Market items are time limited but I'm specifically talking about the event-specific items that require commendations.
For me I love seeing players with limited-time cosmetics as it shows how long they've played and acts as a way of saying 'I was there when X event happened' and that's the way I feel event related cosmetics should be, rewarded to players who were there during that month, as inevitably all those nice looking cosmetics will end up just being another dull, overused cosmetic in a couple months time as everybody will have them, and they'll lose their 'wow' factor. I love seeing other players all those old event cosmetics such as the Kraken skull figurehead and the hungering deep drums as you can say 'wow, they're a dedicated player'. It also provides no sense of urgency as you have forever to unlock them, unlike previous events where you had unlock them during the event.
Anyways that's just my opinion, the new unlocks look great but I can't see myself using them in a month or 2 when everyone will have unlocked them. Really hope Rare doesn't continue this method of releasing event-specific cosmetics in future updates.
Feel free to disagree in replies.
