conseils (en anglais, si quelqu´un peut traduire):
-You cannot switch at the last min to the winning side and have it count a win. It gives you the win\loss for the side youve spent the most time on.
-If you quit early it counts as a loss even if your side wins.
Those are wrong. you are given a win if the team you are on at the end wins - however, you must be on the winning team and have spawned before the round is over. If you quit before the round is over you get a win or loss depending on what your team won/lost.
Does anyone else have anything to add here that has helped them on their way to getting the fabled WC ribbon?
you are correct about keeping a log to know exactly where you are at. (I did) 
- choose your servers carefully.
- turn off ´auto ready´ on the server load screen so you dont auto-spawn.
- when you first join a game dont spawn! because more than likely the game will be already 1/2 through. wait and see how the teams look. if you quit without spawning, you dont receive a win or loss.
- dont play when your too tired.
- try not to quit if your behind: at least play until your +1 wins ahead for the day.
- adjust your player class so that you hit at least 15hrs in each class so you can get your veteran badges. then I recommend playing AT, sniper or assault from there on out while commanding. Later on you will need the actual playing time in other classes to get the repairs/resupply/first aid you need for the expert and harder medals.
- choose your servers carefully.
there are other tips on this I have posted in another thead.
Play with lots of friends or on 16 player servers (I personally dislike anything smaller than 40 players max
)
I´ve got a 2.5 ratio so I should have it in another month or so
considering I already have over 1,300 losses thats not too bad ;)
