One day, I hope to actually play DnD.
wizards, druids and sorcerers aren't archtypically depicted as 'stealth hunters' though, they might be more skilled in magic itself but they haven't dedicated themselves to cultivating that particular skill.The argument is why a ranger would be able to do it automatically and without permission while druids, wizards, and sorcerers despite them being more knowledgeable about magic.
And again, a ranger shouldn't be casting spells withing enemy earshot anyway unless they are started combat.
Hunter's Mark has an hour duration for many reasons.
while i agree in general that they shouldn't intentionally be waiting until earshot sometimes that isn't always a possiblilty, sometimes you find an enemy in your path that you need to take care of and don't want to alert everyone else in the vicinity.
what if the spell i intend to use isn't hunter's mark? a spell that is also not compatible with the use of concentration required for a number of stealth-based spells.
