Not sure why OOO is taking keys away from us. I have been happy with them lately. It would be one thing if there were scheduled breaks from key buying, but that does not appear to be the case based on patch notes. It's not like OOO hasn't been making money from the 1500 ce price tag.
My suggestion, although this belongs in suggestions, is just to make them 2k ce and be done with it. But this is more of a rant so I left it in general discussions.
Well, since you read the patch notes, you must have noticed that how the keys are to be obtained is being evaluated. I am definitely in the camp that feels that a gambling or lottery system for obtaining them is not the best approach. I would rather just pay a specified fee for particular access. Gambling is actually against my belief system, offensive to me, even.
My answer to the problem was to purchase enough keys and materials from those runs to craft the specific gear I want from the Sanctuary. Whatever keys or mats are left over, I'll resell. It meant purchasing energy sooner than I had intended, but the Rose Regalia events did the same. Artificial scarcity certainly feels weird in a video game, but it is important for an MMO, I think.
Planning ahead should be the hallmark of every experienced SK player, yeah?
