Costume store

You could put one in PVP at 1100, or replace the 10-pack of mighty tokens with them on season progression; you could work them in to Simulator progression. You could work them into daily rewards instead of standard and heroic above say 2,000 days of play. There are all kinds of problems you could solve with them.

also remember the goal of advanced tokens on the dev side is to encourage people to put themselves in a situation where they have roster pressure, so you kind of want to give tokens like this to lower tier players as well.

The problem with it being a benefit to players who "don't want to spend CP on Classics" is that it's a detriment to players that are willing, or choose to spend CP elsewhere, because the first group is behaving irrationally.

The primary goal of adding this token is to limit player choice. It doesn't provide a stepping stone the way Mighty tokens fit in between Heroics/Elites and LTs. It's strictly inferior to the equivalent currency (20CP) in terms of flexibility, for both the players AND THE DEVS. 20CP can be spent in multiple places by the players, and likewise, if the Devs wanted to add a "Classic token's value" to rewards, they could drip the extra CP across progression. A couple CP early on to entice players, but the rest of it higher up so that earning it requires more effort (and so that the devs are giving out less rewards overall for every player who doesn't reach that higher reward mark).

Everyone who thinks it would be nice to open Classics from time to time should just do so and stop actively trying to make the player experience worse for everyone else.

The amount of free daily loot boxes a player can open in other games, compared with this one, is just insane.
To earn a CL token somewhere, and even to get a random 5* cover from one of the 73 5*s available, won't have any type of side effect. 
It's not as if you could earn 2 5* LT covers each month (oh, thinking about it, it already exists )
And for people who use to open them, congratulations, double cup for you.

At the risk of sounding ungrateful, the only thing I'm annoyed about is that my free token resulted in me getting a literally free costume (Peggy).  Which was converted into 500 HP.  I don't really care about the HP.  I'd have been happier with a second pull from the vault.  I realize that's slightly hard to code and all, so I get that.

Hopefully any bundles including extra pulls from this vault will A) be released in a timely manner and B ) require in-game currency like HP or CP.

Side note - I don't like to spend dollars on any mobile game, but I cracked and spent $10 on that X-Force Wolvie 8-Bit, just so I could yell Berserker Barrage when I fire his powers.  That costume is great.

This vault was a great idea, but poorly executed and even more poorly communicated. Big fan of everything BCS is doing but this was a swing and miss. I appreciate the free 500hp for my dupe though. For what its worth I would've flipped that 500 on an extra pull all day until I got a fresh costume. Maybe next time!

I believe they are trying to show all the costumes that are available. This way folks might be willing to spend money to get the ones they want later on. Just a form of advertising.

Those weren't all available costumes though, quite a few were missing.
