I've experimented with roundless from time to time but always run into issues with anything metered in rounds, like stun, or bleed, or spells, or maintaining adrenals. . .causing us to benchmark meta rounds, which we realized just put rounds back into play anyway.
How do you work around that?
Ah, the adrenals question. They would essentially be treated like an instant spell or as a one second action (Adrenal Defense would, of course, be an exception once it was active). You could still apply stat bonuses so that people with a negative SD stat bonus would take longer to perform them if you wanted (in which case if an adrenal move was used during another action it would extend or cancel the current action) but I don't think I'd use a initiative rolls or stat bonus on adrenal moves. I doubt I'd make someone cancel their action very often, but it would just have to be a case-by-case judgment call. For example, if you used Adrenal Deflection while making an attack, I would say that it negates any parry you have declared and extends your attack by one second.
