How do you define active? Not that anyone here on the forums can give you an accurate number.
I only have time to play a few hours on the weekend and I spend maybe 1% of that time on fleet. Am I active?
I think they said about 2 million active players that log in regularly and about 10 million that log in less frequently.
I assume the first category consists of people that play several times a week while the latter... several times a month? Or have played within the last 3 months or so?
I doubt we'll ever get more clarification on how they define "active".
