But at the same time, this attitude is very much the type of thing I'm frankly sick of dealing with when I roleplay. When he said it, I wish I would have said, "Why is 'doing cool stuff' limited to the stuff that's on your character sheet? You're telling me your character can't explore, interact, plot, discover, and fight using interesting tactics based on your current capabilities? As if suddenly when you get your next feat/spell/class ability you'll suddenly be able to 'play your character' better?"
I don't know you, and I don't know your game style or adventures.
But, in my experience there are quite a lot of DMs who like to throw "uncool" adventures at low level PCs. "Go kill the rats in the basement". "Go fight some skeletons." And if you don't want to go on that adventure, then you're not playing this week because hey that's the adventure. Typical first level adventures involve "delivering a message" or other paltry tasks. Many published dungeon crawls for first level PCs are "Hey there's some spooky lights in the woods, let's go look!" or "Hey guys let's poke around those old ruins at the edge of town".
There's an entire
philosophy built on the idea that "In order to do cool things (at higher levels) you gotta earn your lumps being a nobody because that's who you are at level 1, a farmer who picked up a sword". Some may like it, but I find it condescending. "Aww he thinks he's a hero! Here, go fight some skeletons".
As a player I want to save the kingdom, not some farmer. I want to slay epic beasts of myth, not rats. I want to devise cunning defense strategies, stealth missions or clever cons, but those plans are wasted on the types of threats often thrown at low level PCs, because not only are those threats able to be overcome easily, but rarely is one in a situation to unleash those plans in the first place. I want to explore far and wide, and exploring as a 1st level PC means getting eaten up by powerful stuff in other areas.
Then there's the capabilities. If I'm a mage, it's "cool" to blow things up, to polymorph enemies into chickens, to dominate my enemies, to throw curses and summon great monsters. I can't really
do that with the capabilities presented to a first level spellcaster. "Hey guys I can cast magic missile and summon a dire rat! They shall
fear me."
As a DM, I try very hard to give a real serious, and important, tone to what the characters are doing - even at level 1.
