Hi there~

I would like to share some ideas to make Iron Lockboxes more interesting~
They have the potential to make a lot of money for OOO, but right now such Lockboxes just aren't attractive enough.
So here are some ideas to change that:

Bigger variety
At the moment there are only 2 types of Lockboxes that need a key to open. Those are the Iron Lockboxes and Mirrored Lockboxes. Both are acquired through the price wheel at the end of a level.
There should be more different Lockboxes, each with their own rewards~
For example they could be divided by color (each color could represent the type of accessory you could get, like red boxes have toasty accessories, yellow boxes have regal accessories, etc.) or by number~
That way people could focus on a specific type of box to get that what they want~

More information
It's not that easy to find a list with items that could be in an Iron Lockbox. Not even the wiki has information listed about that.
Even if there would be a list in the wiki, not everyone bothers to search for that.
That is a big issue. If someone doesn't know what's inside those boxes he probably won't spend money on it.
So there should be a list in-game, in the description of the box, that tells you what you can get out of them.

Better accessibility
Iron Lockboxes are way to rare. They have be be much more common.
If someone gets more boxes regularly they would be more tempted to just open some, especially once the price would go down in the AH.
But only make Iron Lockboxes more common; Mirrored Lockboxes can stay as rare as they are now.

Those are all the ideas that I can offer right now~
I don't know if someone already posted something like that, and I can't really check it either because I don't trust the search feature. (Only a few days ago I wanted to search for a Black Kat Cowl. The search didn't show any results, but I could find at least 3 posts in the Bazaar with people who wanted to sell one)
Also, all those ideas were inspired by Team Fortress 2~ And don't say something like "it's a bad idea to do it like TF2" because Valve actually makes enough money with selling keys, hats, etc. so that they made TF2 F2P~
