Agree with everything here. The investments in old ABs were made with an expectation of permanent rewards at a consistent frequency. Rotating them is the same as decreasing their frequency. That violates expectations and is not fair.
Even more worrying in the long term - any investment in new ABs must now come with the expectation these ABs will be rotated and show up less than 1x per month (at least eventually). Maybe they’ll even get rotated out entirely. This provide way less motivation to do things like R9 multiple characters for them — since there is no longer any guarantee of breaking even on those investments, let alone a guarantee of positive ROI, even in the very long term.
We are a patient player base that buys into long term investment, but now you’re taking away our ability to predict with confidence. That means the ability to confidently plan and make informed decisions are now gone. This undermines the very thing so many of us players enjoy.
