This Is the crux of the issue
You were not going to get a free skill at level 13.
You are not going to get a extra feet at level 13.
You were not going to get bonus action options at level 13.
but you do now get something at level 13, and it's a naughty word feature that you do not want and you didn't ask for.
and everything you get at levels 1,13,17 and 20 that is tied to HM is payed by not getting something else.
It's class resource pool.
those 4 abilities cost something in "class feature point pool", whatever value that is.
you could be getting something else for that value.
Those would have increased the power of the Ranger class and made it not backwards compatible.
and?
and are all classes backwards compatible?
sure you can use them, but I'm not sure how 2014 monk would feel next to 2024 monk...
Yes it is.
The averages are the same.
2014 has a higher base ceiling but a lower base floor.
2024 has a higher base floor but a lower base ceiling.
They both averaged to the same math. It is just easier to make a good character in 2024. 2014 you have to optimize to get a good character but that optimization is rewarded more due to higher numbers and additional loopholes.
so not the same math.
There are no first level Ranger spells that are combat equivalent that is built into its damage calculation.
There are no other first level damn it spells for Ranger in their calculation. It's just Hunter's Mark.
Zephyra Strike was cut. that's on purpose.
Level 13 is where you get your first fourth level spell. This gives you enough Second Third and Fourth level spells to cast one of them every encounter.
That is when your first level spells age out of the damage calculation.
But now you get a new class feature that buffs your first level damage spell and now it becomes an option again.
The feature is not forcing you to use Hunter's Mark.
The feature is allowing you to use Hunter's work.
Because at level 13 if not buffed Hunter's Mark is not worth casting.
At level 13 a full caster's first and second level spells are not good enough for damage.
At level 13 a half caster's first level spells are not good enough for damage.
The 13th and 17th level features allow your only good offensive first level spell to be useful at those levels..
Think of it like this imagine if the sorcerer got free castings of burning hands. Burning hands eventually is not good enough damage to be used against the monsters that a sorcerer faces at Tier 3. But if they got an ability that increased the damage of burning hands burning hands becomes an option again. Force they're not forced to use only burning hands. Burning hands just doesn't suck anymore.
That's what they did with Hunter's Mark. Hunter's Mark doesn't match up well enough to other Ranger buffs and summons at higher levels. But you still have first level slots. So they buffed the strength of those first level slots vis a buff to the spell.
This is the problem.
I would not mind getting burning hands on a ranger and some features than buff it later.
Or getting divine strength instead of HM.
or getting cure wounds instead of HM,
problem is when mandatory spell uses your concentration slot which is very valuable resource.
when you give out usages of spells per short/long rest and especially when you lock several class features to that spell, that spell better be worth is or make sure you can ignore concentration tag on that spell.
otherwise it's limiting for your play options.
