Oddly enough this is the one point I can't get anyone to explain to me logically.
I get "this is only going to happen once, they'll never do it again." If they associate the gear's introduction with increased cash for gold sales, you bet your ass they will.
Some people think that Legendaries have higher stats than Exotics.
Some at least admit its for the treadmill locusts, but still remain entirely convinced ArenaNet's not going to turn the game into a treadmill.
The issue is, even people get on board with this, if it generates revenue, then all it will do is shape future development of the game.
"Why are the cash shop sales so low? What's this spike here in the data?"
"That's when we introduced the Ascended gear."
"Well, can't you do that again? Numbers for next quarter have to look good."
