That is a decision FC took a long time ago, under Sil's lead. You may debate whether that decision was good for the game, or bad. I would even go as far as admitting that quite likely, it was bad. But that was long in the past, and now we are here with a game that has gone pretty far down the WoW route. I find the proposition that this choice is reversible without major investment into marketing debatable, to say the least.
But if it is reversible at least to a limited extent, this can only come from PvP. AoC once had a healthy PvP population and a few (by no means many) players may return to check out PvP updates. By contrast, AoC never was a crafting-focused game. Trying to sell an old game on something that never was among its strong points also strikes me as a dubious proposition.
All true, but it's the only data we ever saw. If I had the choice between low quality data and mere guessing, I generally find it hard to completely throw the data out of the window.
