The monk has never been an "all-in offense" character since he has features that relate to a more defensive strategy. In terms of defenses against effects, the monk has pretty much all classes beat hands down.Problem is, the Monk's damage is lackluster (about Treantmonk's baseline damage for levels 1-9 if you go all-in on offense). If you took the Mobile feat instead of boosting Dex, it's even worse.
Adding a minor effect to bad damage doesn't save a class that has poor tanking, no spells, poor utility, and poor control.
But it's strange we even put down a term like "baseline damage." If we want to talk about bad baseline damage, wizards and bards are horrible. But damage isn't the only part of the picture.
Poor tanking? They have proficiency in all saves, the lowest possible saving throw modifier they'll have at max level is 5. They can also reroll failed saves. They can also resist all damage except force for 1/5th of their encounter resources. And enemies will permanently have disadvantage on them for the rest of the fight, too. And they can't be targeted by most spells like magic missile. And they have deflect missile which turns the enemies DPS against them, by a small amount.
No spells? checks monk's section to make sure my eyes didn't deceive me. They have Astral Projection, a ninth-level spell that uses material components for 2/5ths of an encounter's resource.
Poor utility? And their tongue of sun and moon never comes in handy? Invisibility without concentration isn't good utility? How about doubling jump distance for 1/3 of an encounter's resources? Not needing food and water? Not to mention the buttload of utility that the subclasses grant, especially shadow and elemonks.
Poor control? They can basically determine which monster ever gets to move and attack if they're left to roam free a battlefield without contest, which they can with Bonus Action disengage.
I have never, ever, experienced any of these problems in my 3 campaigns I've played monk. 1 from level 1-7, the other two at higher levels 13-18 amd 16-20. Never, not once, have I felt I was a poor class that didn't functionally work. If I was looking for damage and pure damage, I would've chosen barbarian. I didn't want pure damage, though, I wanted to be an effective skirmisher and mage killer while also having the ability to apply debuffs that the whole party can benefit from.
