In my experience rangers are at their best when they focus on archery, but sure, melee rangers exist. Generally, melee rangers get less out of hunter's mark than ranged rangers do. Melee rangers are probably better off concentrating on something like Zephyr strike. But anyway, this part of the discussion is pretty tangential.
How is the warlock's resource more limited? If the thing they are choosing to concentrate on is Hex, which is a bad idea most of the time, after tier 1, but set that aside since monks also can't do the things warlocks should be doing instead, they can have it up pretty much all the time, because it lasts so long, and their spell slots refresh on short rests.
Challenging fights, almost without exception, have around as many monsters as PCs, or perhaps more; not fewer.
I don't even need two spells per fight to out-control stunning strike. Phantasmal Force / Suggestion / Hypnotic Pattern / Banishment... even Hold Monster --- all of those have a higher expected value in a single casting than stunning strike can be expected to do in a whole encounter.
People keep saying that I'm mono-focused on DPR. Are you not reading my posts?
3 to 6 rounds with how many monsters? Rounds per enemy is 'rounds the fight lasts' divided by 'number of enemies'.
It's not about who understands the game; it's about discussing in good faith with transparency, vs hand-waving and moving goal posts.
A level 8 monk will stun 3-4 times per short rest of dumping ki into stunning.
That’s 9-12 times per day. Hypnotic pattern directed at 4 enemies may incapacitate 3 or so. On average that’s about 6 rounds of incapacitation. (Assuming a 4 round fight).
To come out even you’d need to target 8 to 12 enemies with hypnotic pattern per day. That’s probably around 2-4 casts of it. That’s doable by level 8... but the monk will do more damage than any character that can do that at level 8.
There’s a few more factors to consider in the analysis but this is a starting point.
