There will be chaos and I'll make sure the favour is on our side muahaha All you filthy races are unworthy of the eldar.
Indeed, most Chaos warriors don't bother with hygiene. We're completely filthy from the head to toe in Eldar guts and gore, which is exactly why we'll flatten your armies under all our filth. We may not be worthy, but at least we'll achieve dominance over the galaxy before you can.
It's time to put a stop to human dominion over the galaxy, the imperium shall fall, the filth of chaos purged, and the green bacteria of orkz cleansed.
Just as with the table top. Space Marine armies will numerically out weigh the player count of other factions by quite a bit. Aside from that from keeping tabs on where the large clans are going on this game it seems most of the ultra competitive clans are all siding with "Space Marines". I believe Chaos will come in a strong second but just due to the sheer numbers and the large-scale clans that are moving into the space marine faction I do believe they will have a large advantage in organization and numbers. There is still quite a ways to go though over the next year and a half+. So we'll see what other large scale clans come over and which faction they choose to settle into.
For reasons I'll never understand people prefer the space marines instead of the awesome orks so the SM will probably have the biggest populations near launch unless the F2P ork system makes up the difference While Eldar might not be super popular with the crowds here on the forum they might be the dark horse faction for the general MMO audience since people love elves and sleek clean designs
