The monk is doing 29% more damage than the fighter (I’m showing it this way because that goes i did it before so just being consistent).Okay, so the Fighter drops the shield, pulls out a Greatsword and does 2d6+3 which is 10 damage, and does 3 damage on a miss. Assuming a 60% chance to hit that ends up having monk and fighter look like this
Monk:
1d6+3 x 2 x0.6 = 7.8
1d4 x 0.6 = 1.5
Total = 9.3 damage
Fighter:
2d6+3 x0.6 = 6
3 x0.4 = 1.2
7.2 total.
That is only 33% less damage, and the fighter has the same AC, better hp, second wind AND THE DUELING FIGHTING STYLE.
Yes, with this single combo of handaxe and dagger, at level 1, a monk can make three attacks and that is very powerful. But with anything else not using the weapon mastery, they are going to drop behind. And as the levels climb, they start losing. And... they can't change tactics. Their tactics are baked into the class.
To put it in perspective, the flex mastery gives that dueling fighter with a long sword an effective 1 damage boost (from 9.5 to 10.5, though technically a little bit more with crits). That’s a 10.5% boost to damage, and people are calling flex “garbage”.
So there’s nothing small about a 29% boost in damage.
Now is the fighter more flexible in their combat options, absolutely. I mean they are supposed to be the master of combat, I would hope so.
But people act like this monk is bad at combat at low levels…and that is demonstrably false. It’s not until 5th level or so that you start to see it’s decline.
