- Is X nerf too strong?
- Does this affect many people's playstyle?
- Does this affect daily activities for many players?
- If the backlash is strong, do we have a plan? Do we rollback?
- Are the prepared PR statements sufficiently satisfying and detailed? (yes, PR releases can be a testing artifact, in a sense)
To me, those points should be studied before starting the development of the features... in a timeline ... earlier than testing.
