Danger Missions are supposed to be an extra challenge and to break the monotony of running FSC all day erryday, right? They also have low crown payout, are playable only once a day, and have strict joining party rules to make sure you don't exploit them. To make up for this, they give you a lot of prestige.
I say this is not good enough. If these missions are supposed to be extra difficulty and not necessarily profitable (similar to Shadow Lairs), give them a better reward. Something that says to everyone, "I completed this really hard mission". The easiest way to do this is with costumes, since they can stand out from the crowd and no one has to worry about balancing issues, or even creating multiple versions of the item.

So, you ask, what costumes would be rewards for a danger mission? The answer is simple: Recon Armor!

All the Danger missions have the same basic premise: a problem arises deep in the clockworks, and the Elite recon rangers are called to deal with the threat. Then Desna invites you to come along for the ride. She basically gives you honorary membership into the Elite Recon Rangers. After proving that you have what it takes to be a part of the ERR, Desna should give you a set of armor marking your official membership as a Ranger.

How getting the armors would work:
After completing a danger mission, knights would receive 1-4 tokens, similar to Boss Tokens. However, instead of getting a different amount of tokens based on how much of the mission you played, you MUST have completed the WHOLE MISSION to get ANY tokens, and the amount of tokens you get is instead based on how many people are in the party. This makes it more of a reward the harder the mission is. 1 token each of you did it with a full party, 2 for each if you did it with three people, 3 if you did it with two, and finally 4 for soloing. This way, you can obtain rewards faster (and therefore, must be better at the mission) if you can manage to solo it every time. The tokens would be placed at the end of the second level, after the final room but before the elevator to the Treasure level. After collecting enough tokens, they could be taken to Desna (somewhere in Haven, most likely in the Arcade) and traded in for Recon Gear. The tokens and gear would be mission- specific, and each piece of armor would cost 20 tokens. I chose a high cost so it takes a long time to get if you take the easy way out and ask all your overpowered friends to come help you, but it only takes 5 runs if you do it yourself.

The rewards would be as follows: (remember everything costs 20 tokens.) (Descriptions are a bit repetitive, I apologize.)

--[combo tokens]-- (Not sure if this is possible, but):

::Recon Pack::
-The pack carried by all Recon squad members. This pack symbolizes your acceptance into the ranks of the Elite Recon Rangers.
-Cost 10 of each token (can you do this?)
-Looks like the Recon Module in LD but is purely cosmetic

::Recon Crest::
-a badge that conveys your status as a member of the ERR. Wear it with pride.
-Costs 5 of each token
-crest with recon logo

NOTE: The reason I used 3* armors and not 5* as you might think I would is twofold. First, you are only an honorary member of the ERR and therefore would it have high rank. Second, and most obvious, these are the items seen in the Danger Mission Lobbies. :P

Side note: I would also like to have achievements for completion of each danger mission, each mission solo, and each mission without dying.

UPDATE: got screenshots for most of the items, as stated the models are already in the game. All that needs to be done is to make them available to us.
