A bit late to the discussion, but in living world 4e, it was not unusual for DM to post every defence, AC and monster basic attack so that players could narrate if they hit or miss, roll OA for monsters (with easy retcon from DM if the monster wouldn't take it due some punishment mechanics) and some even went so far to add bloodied or death effects and HP.
It enabled a bit of meta - when you saw the monster had high reflex, low will, you could target that defense - but in general, it sped up play. I've also seen google sheets used as maps - not because they were detailed, but because it was easy for players to log in, move their characters (letters on a grid) and/or mark area effects in various colors. Everyone could then see current situation - in 4e there was a lot of forced movement.
So, I agree with the proposal to just post monster CON save. It will let us all know if we have advantage after topple and not have to wait on you.
