I do not like it, it feels like we changed one demon for another with these changes, if they keep it as is. I would change it into something like this.
Remake all manuals into single affix manuals.
With that players can select specific manual they want.
Then make the affix range from min(lowest rarity manual) to max(highest rarity manual) from whats in game right now for rerolling purpose.
When rerolling add [before/after] image with “No Change” and “Accept” button. With NO animation, its cool the first time then it just takes time.
Make “No Change” default if you click outside/close/DC etc.
Bonus, changing Affixes at Occultist should also default to “No Change”.
With these changes, when players find, lets say Movement Speed they can temper it right away, knowing that they will get it. But also make players wanna reroll to get higher values, for minmaxing. But also get the option to cancel “No Change” the reroll if the value is lower.
Should also be easier to balance, add and remove manuals in the future. While giving players the choice of what they want.
