Like, is there a worse first level experience than playing a monk? It doesn't exactly sell new players on the class.
1st level ranger or rogue?
I did like my 5e monk. AC 15 and 1d8+3 + 1d4 + 3 at will damage is actually very very high. A ranger has nothing substantial at level 1.
Edit: new twf rules already buff monk survivability. They can now dodge or dash as a bonus action and still have a off hand attack. A very substantial boost to survivability if they need it.
