There are two class features, Perfect Self (PHB p. 79), and Relentless (PHB p.74), which contain the phrase 'when you roll for initiative.' Both allow the character to recover some expendable resources.
When using initiative variants (DMG p. 270-271), what's the best way to interpret this?
As written, these characters would gain their superiority dice much more frequently, or much less, depending on which variant you use. This doesn't feel right to me. Should I read the phrase 'when you roll for initiative' to mean 'when a combat encounter begins'?
What would be the negative consequences of making that substitution?
