A "holdup" is the exact reason they're not - as in "holdup the player by increasing grind for the sake of grind". You still had to work for Etheric Light - but it was a true reward in and of itself that served a definite and measurable purpose (though as a PVE-only player I would have loved there to be one or two more avenues to acquire it in the run of a week, but I digress). Going to post the link to a new Forbes article here too (already did it in another thread) as it pertains directly to this topic: http://www.forbes.com/sites/insertcoin/2016/02/08/why-destinys-economy-shouldnt-remain-rooted-in-infusion/#e92a6e270655 Two relatively well-written articles via Forbes in one week? I know ... it's a bit unsettling.
