This.
I'm a player since day-one. 10.6k hours. And yet...
...I haven't used a credit card to buy anything (other than the expansions) since probably 2013? I don't even know how Anet makes money off me. I've maybe spent $200 since 2012. I don't like EoD, but I don't care about the money I spent. $30 is lunch money to me. Raiding and/or platform gaming, in general, has never appealed to me. "Stand in circle 'A' and do 'X'. Then move to circle 'B' and do 'Y'. Ad nauseum. Rinse and repeat.
But the real question would seem to be, How many long hardcore, "Raiders" actually spend money in the game? Most of them probably - like me - have thousands of gold (and ascended mats that can be converted to gold at any time) in the bank from just playing the game.
It will be interesting to see how this plays out. How far down the path they go to Raid Nirvana.
I will say that the best thing about EoD is that, if I don't do it to completion, I'll miss exactly nothing.
