Read my posts. I am complaining because I am a sorcerer and our spells known list is extremely small. Stop equating arcane power = wizard. There have been other editions since 2nd dude.
First of all, 4E doesn't count as an edition of D&D for the purposes of design iteration. It was intentionally designed to be as far removed from every other edition as possible, and is entirely irrelevant outside of its own context. The 5E sorcerer has more in common with the 3E wizard than either has with any 4E class.
Second of all, that
is a much more coherent argument. You think that it's unfair that so many monsters are immune to fire, because you picked a weird gimmick class that only knows like twelve spells. And instead of working to fix the class so that it's less gimmicky, you want to fix every single monster in the game that would otherwise be able to bypass your gimmick.
Burning a fire elemental will always be ridiculous, and nothing you can say will ever change that. Why don't you just learn Magic Missile as one of your spells? Or learn Chill Touch as one of your cantrips? Even if you only know a handful of spells, refusing to pick a non-fire attack spell still seems suicidally foolish. I mean, yeah, the cost is higher for you than it would be for a wizard... but that's no excuse to not pay the price. Limited spell selection is
the balancing factor for the class.
You don't see the barbarian player complaining that their class features are useless when they have to pick up a bow in order to fight a dragon. You still get your proficiency bonus to hit with weapon attacks, even as a sorcerer, so you should never be in a situation where you
can't contribute. You just need to accept that
sometimes the circumstances are working against you, and someone else gets to be the star of that encounter.
Because the alternative - burning fire elementals to death - is ridiculous.
