This may not correlate. Lower revenue doesn't necessarily mean the loss of players. It could be that the player base is relatively stable, but just aren't purchasing anything. I still believe that players gravitate toward those events that bring them the most gold per hour and that those players never need to spend real money on anything as they have plenty of gold to convert to gems. I agree, but with provisos. WvW, PvP, and high-end content (hard-core) are the least populated in the game. Best guess based on surveys is a smaller portion of the player base. However, I suspect that the hard-core players average per player spending in the gem store is significantly higher than the spending of the more casual population in open world. So, while I don't think they should focus heavily on those players, they should probably focus more highly than they do on them. (See my post on finances and communication somewhere on page four.)You also have to think about how much effort it is to keep each player happy and spending money. If I were to wager, i would bet that casuals require significantly less effort to please and extract money from and significantly outnumber hard core players.
