A ki-less monk doesn't really have something equivalent to eldritch blast to fall back on.
That's why I asked if people expects the Monk to be able to use Ki each round.
When Ki is depleted, if I read it correctly the Monk falls back to using her bonus action for an extra unarmed strike. That's not as powerful as an extra attack because the damage is only 1d4+mod, but it's still roughly like "half an extra attack" each round.
