BF3 player count PC

Hi guys,

I must've put more than 1.000 in BF3 on XBOX 360 in my teenage years. I purchased BF3 on PC for the sake of nostalgia 2 years ago but then never really got to play it  a lot due to personal reasons. I just redownload the game only to find out that there are no full servers? Is there any particular time of the day (EU servers) when there are more players? Honestly I am quite disappointed with the number of players. I know this is a very old game now but thought there would at least be 4/5 full servers?

Usually there is just 1 metro map and then another russian server, all other servers show incorrect player count it seems.
