can you give us a session link ?

EX :http://farcry.trackbase.net/?mod=playerinfo&idx=26

1) no xp recorded = specs
2) too many bots are playing
3) session lenght not long enough .. (need at least 1/3 of map time played (in general.. ) with real players)
4)not sure on farcry but a minimum of 6 players is needed to get rating (without bots or maybe 1-2 bots allowed again not sure)

Example ranked sessions : http://farcry.trackbase.net/index.ph...nfo&idx=951696

Globally thats it .
