I havent been here for a while, but when i log in on EU1 this days its barelly 10 ppl on it and thats like only battle serwer for eu. In old days EU1 was always filled with minimum 50 ppl on it and now its empty.
To finally answer your question, the average multiplier is higher on EU2 since the last Conquest patch. EU1 tends to have less players than EU2 since then, and the people who never played on any other server but EU1 think the mod is dying because their one and only home is less crowded than before.
The total number of players is fluctuating a lot, which you can see on the player count displayed on the website. It is often inaccurate however. Last time I looked, it said there are 132 players online, but there was a Strat battle on EU3 with 80 players, EU1 with 25 players and Siege with 50 players. Adding together the EU servers only without even looking at NA, OC and CN shows there have been more than 132.
