Well, how about the following then:

All Fight

True monks know the value of time and being efficient, and therefore try to deal with as many enemies as possible at once. When damaging an enemy, if that enemy has not been damaged by the Monk in same round, the damage is increased by (5 + 5 for each enemy in 2 range)% and it generates (2 + 1 for each enemy in 2 range) Ki for the user.

Like this, it sticks to the plan, while being a buff overall that affects fights where the Monk is being surrounded. So this is a minimum of 5% and a maximum of 45% damage on All Fight's proc, depending on the situation over being a free damage buff.

NOTE: 45% damage will be with 9-ish enemies around you. So this way if they want to hit a meaty Setting Sun, they'd need to risk it and get into melee, instead of playing volleyball with Ki blasts. Monk is a melee class, and this buff would incentivize that behavior.
