Just wanted to say that I would like the "ready action" action be implemented as well. It's especially important for rogues, because they want to leverage sneak attack as much as possible, but yet they have high dexterity, so high initiative: they go first when nobody is close to nobody. In dnd 5e, the usual way to deal with that is to say "I move there. I ready action: fire at that opponent, triggered when someone gets 5 feet from them". But currently, we can't do anything like that, and it severely impacts rogues viability in action economy (they have to waste a turn, which is huge in 5e with battles lasting for 2 or 3 rounds).
I'm not exactly sure how "ready action" would translate as a video game feature, though, it sounds tricky. I guess that alternatively, getting back the "hold turn" from 3.5e/pathfinder would be OK (better mixing rulesets than breaking balance).
Thanks, I love what I'm seeing so far!
