I don't think you can find data to compare how fast this game is losing players compared to other games. However, it's not that hard to figure out that the game is in a decline, check the revenue reports, the gw2efficiency episode completion rates, even the leaderboard for the Beetle race of Dragon Bash which had way more "competition", shall I say it? Population IS declining, there is plenty of data to support that, and if you believe otherwise, I'd like to see any kind of data that supports that. Sure, the population may be declining, but to say that the game is "bleeding players faster than any other MMO" is hyperbole at best as it is unfounded by any statistics that are available to the general public.
