My next character will probably be a fighter, so I might have to try this!
It is pretty boss in tier 1. With action surge and nick you could do 3 attacks a round every round and 4 when you action surge. You do have to invest in Wisdom though, which means a lower Constitution if you are on point buy.
That is a really good trade in my opinion though if you want to be a better PC overall, as Constitution is the most useless ability generally.
The other thing the Monk dip does is open up a lot of other weapons to a Dex build - hand axes, spears, sickle, light hammer, quarterstaff .....
