I think Igors point was that a large map game takes longer to finish due to map size than a small map game. So you can potentially play 3-4 small map games in the time you can play 1 big map game (or even 10-15 games if the large map game has a long time between turns and a large number of players). The ELO system doesn't take than into account so if you want to rank-monger you are better off playing a lot of games on small maps.
As far as ranking points goes, do you decide the points when the game starts or ends since a players ranking may change a lot if a game takes 20-25 days to complete.
Lastly, does the system encourage/reward players for playing a variety of opponents? In other words can you get a ton of points by simply playing 10 simultaneous games with 1 other player and winning all 10? A better way would be to only allow 1 ladder game at a time with another player otherwise this is another way to rank-monger.
Unfortunately there isn't a nice easy solution like chess (where you only acquire points in tournaments and are only playing 1 game at a time and all games are the same in terms of board size/pieces).
