You know, say what you will about GW's playerbase, but I have noticed that they are generally quite... anally hardcore? :-p Yeah, even...especially the PvE folks.
I don't know how other pay-to-play games like WoW has it, but I've been reading some general whining on the PWI/STO forums about grab bag items and how the players demand transparency from the devs on the percentages of certain rewards.
And I can't just help but compare it to the Guild Wars fan base, which instead of demanding hard numbers...start tallying up the #'s themselves across large numbers of people, and then estimate a drop rate/spawn rate/etc. from there which then gets posted to the wiki or wiki discussion page. Now, yes, I do get that there is a difference here in that the GW players are crunching numbers on largely non-purchased stuff (drop rates, spawn rates, holiday mystery box rates, etc.) But given how fast the grab boxes in STO/PWI sell (only the keys need to be purchased with $$), I don't think there are any less sources of datapoints there either; just no one getting together to crunch some numbers.
Even in general, the GW wiki (and related wikis like PvX) is a pretty awe-inspiring place. Quick updates, complete records of every bit of minutae in the game, strategy suggestions that get updated according to game/skill balance, statistical analysis of all sorts of stuff...
They're all free-to-play games. But what's so unique about the GW crop of players?
