The orb change wouldn't be so negatively recieved if you didn't tie elements to it and said how much it costs
I'm in the minority and see no problem with the change except removing it from masterworks I don't think that was wise but I have to see it to make a decision. Don't tie it elements that in my opinion is not a smart move. It shouldn't cost more then 2 points of energy ,free if I'm being biased. This change still aggravates the vault issue which you have not responded to, either flat out say no or fix it. I'm not one for surprises and ultimately hate then I rather know everything now than be blindsided.
