Not sure a ladder system is something that could be implemented easily. But isn't there websites where you can set up your own ladders for games still? (I used to frequent them back in the good ol'CC days

)
There's nothing preventing anyone to setup a ladder website but without integration we're reliant on players to report their games results. That's also something that could be explored but there are a number of obvious caveats there too:
- Website accounts and game accounts are not linked. How to verify account ownership?
- What strategy for reporting game results:
- One player reports the result? What if the other player contests these results?
- Two players report the results? What if the reports don't match?
- What should be reported? Map settings / winning turn / player perks, races / etc...
- If players have to enter all that data manually, it's going to be tedious.
If you have a good working example to share, by all mean do!
[edit] keep in mind that this is not (only) a self interested endeavour in order to have a bit of competition, it is also a requirement in order to have at least some basic matchmaking feature that would allow players to find other players at their level. I'm doing my best to encourage new players when I encounter them but I'm not going to hold back either. Getting the crap beaten out of you isn't the best to achieve retention for new players...
I would very much like to hear some more specific ideas on how to improve the lobby for MP games.
The main issue I have with the lobby is that you can
either:
- Have a bit of fun in SP and be unavailable for MP games
- Wait for MP games in the lobby and do nothing else
In short: it would be nice to have access to the lobby from a SP game.
