Well if we do not care about balance, then we can also just let the ranger kill an enemy they are tracking with 1 attack? Also feels flavourfull.Wow. Yeah i disagree completely, and frankly i doubt we will reach any common ground. We rarely do when it comes to the ranger anyway.
Anyway the problem with all hunters marks is thst the spell is bland, makes ranger gameplay frustrating, and scales in a way that is meaningless for many tables or just certain adventuring days.
Regardless of balance at different levels, the simplest fix is to add a feature that works alongside it while being more flavorful, and waiting for later levels to be directly punchy.
Most 5E class features etc. are meaningless for certain adventuring days:
- Some tables dont take short rests because the GMs dont like it / feel like they cant take 1 hour to waste.
- Some tables have 1 fight per adventuring day.
- Some tables 1 fight per short rest.
This is a 5E problem not a Ranger problem. And many class features dont matter for some of these situations.
The Hunter's mark spell is the "default spell" which just works and is reliable so it needs to be to some degree bland. The same as the "Divine smite" spell for the paladin. Its there to make sure you always have something useful to do, even if its not optimal and flashy, and the Hunter's mark here is definitly less bland than the paladin one, since it also gives non combat advantages.
And having this bland spell as a backup/default (which does not even need spell slots most of the time), allows you to take many really situational spells as Ranger, since you can always do the bland damage up spell. This allows to NOT be frustrated when you have no use for your situational spells.
