Elfcrusher said:The specific case I'm thinking of is using Shield Master to Shove action to knock an enemy prone. If you are right before the enemy in the Initiative order then it's practically useless; if you can take your Shove action after the enemy's turn it could be invaluable.
Ready an action to shove the enemy as a response to it starting its turn.
I'm sure there is a reason behind it but the lack of delay seems like a oversight to me. To answer, as far as I know, no there isn't. In your particular example, adding a grapple in to keep them down might help.
RAW, there's not many ways to pull Initiative Shenanigans like this, and it's a decision I certainly appreciate personally. In the narrative, there's no such thing as turns or initiative, everyone's just going as fast as they can.
