While I don't think this adds much insight to the topic, I am not sure if we're going to see any changes in the short term. There are a lot of complaints and a lot of backlash, but I don't think that's enough to compensate for the people who have taken the bait and tried to get the shadow keys. Just as a note:
Someone spent $150 worth of energy on the lockboxes and had no key.
I think I have heard other figures thrown around like $40 or $50 from one player.
More and more players are popping up with mercurial suits and snarbolax sets. I would not be surprised if within a month we'll have players who have made it to the shadow lair version of the firestorm citadel.
Shadow keys are selling like hot items off the auction house.
My point is there are many people that hate this update, but there are enough people who are (perhaps grudgingly) buying into the system to make it viable and profitable for OOO. I can't really speculate on their financial status, though.
If everyone was to simply have ignored this new update, THEN maybe there would have been a change, at least to the gambling aspect. I do wonder how this will work in the long-term, however. Will people become disinterested in the investment? Will SK run out of big spenders who are willing to dump $150 in the game on the fly? And is it worth it to alienate the big spenders by giving them no reward for their $150? As a model, is it better to attract all the people who are one-time splurgers, or is it better to attract them as long-term customers who spend small, yet consistent amounts? This seems to be working short-term but as a long-term thing it may not be sustainable as a practice. The worrisome thing is that if this works well enough, do you think all the upcoming, end-game content will be dependent upon a gambling aspect?
I saw that the complaints had nowhere to go once I saw how much Shadow Lair divers were successfully selling Snarbolax sets for in the Bazaar.
People are willing to spend so much on the Shadow Lair armor that it can fund a person's Lair run even if they wanted to solo it. Let that sink in first...
