Not to the sane extent
Fighters beating most classes at combat except two barbarians.
Monk 5 vs fighter 5.
Monk, 18 dex, 14 con, with grappler (doesn't do much for this fight)
Fighter, 18 Ste, 16 con, with Great Weapon Master, using graze.
Figher, 17 AC, attacks with 2d6+4+3
25% chance to miss twice
50% chance to hit once dealing 14 - 14.5 deflect = 0 damage
25% chance to hit twice for 14 damage
= 3.5 damage per round.
38 HP - 14 damage action surge (use after you hit once)
Vs 14 HP = 4 rounds to kill the monk.
Monk, 17 AC, attacks with 1d8+4, 4 attacks per round.
8.5 * 4 * 50% = 17 damage a round.
Vs 49 HP + 3d10+15
= 80.5 total HP
= 4.7352941176 round to kill the fighter
Seems like the fighter would win a stand still and attack battle. But standing still isn't exactly playing to the monks strength.
Or the monk can just kite. The lower the damage per round (i.e. ranged) the longer they last.
