That's right, ready is platform dependent. Imo, it's not really missed in BG3 as it currently plays.
Dodge is matching action to Help, not many people are asking for that one. These are tactical actions that are currently simulated by withdrawing a distance to trigger enemies to dash, or simply bonus action hiding.
Dodge's place in the monk class deserves special consideration.
Sure, the extra tactical edge Help and Dodge give would be appreciated by us with rules mastery. But I'd want monsters to use or account for these too, I wouldn't want an edge to become exploit.
