Uh... No? What are you even talking about, barbarians generally wear little or no armor.
>Also people casting magic stronger because they're angry is a pretty common trope too.
You're thinking of wild magic sorcerer.
Dude, balance has to come from somewhere. You DO have options for making a spellcaster heavy armor wearing barb, but you just can't by default. Why? The same reason any class has it's own limitations and advantages. D&D isn't a freeform do-what-you-want game and it isn't trying to be. Go play GURPS or whatever.

Show me one

In animu maybe
yeah I'm tired of people thinking that
I got into a fight with the DM over whether calm emotions ended rage or not
What's the chance of rolling a critical on at least one of six attacks?
Figured. I prioritized elemental Adept because of fire draconic at level 4.
>arbitrarily limiting character concepts.
Sure, in the same way that rogues being unable to sneak effectively in heavy armour is arbitrarily limiting character concepts. Or being unable to cast two concentration spells at once is limiting.
Rage is a solid ability that has no reason to let you cast spells. If you're using it, you're using it to do melee weapon attacks. Why are you trying to Rage and cast spells at the same time anyway? If you got some bonus to them I'd understand, but it's like turning out the lights and then complaining you're arbitrarily unable to see.
>If a spell has a casting time of a minute, and you do in combat, that's 6 turns. But does it take up your entire turn (I'm presuming so) or do you get a bonus action? Do you get reactions?
It's 10 turns and I'd rule that no, it takes your entire turn.
>But the heavy armor wielding barbarian is a common staple of fantasy storytelling.
The unarmoured berserk warrior is probably more common (the term 'berserk' probably originated with norse warriors that went into battle wearing bear-skins), though it is true that there are armoured barbarian types.
>Also people casting magic stronger because they're angry is a pretty common trope too.
It's not just being angry, it's a mindless rage where you can't focus on anything except hitting people.
>And moreover, it's just arbitrarily limiting character concepts.
It's no more arbitrary than any other restriction like not giving wizards heavy armour proficiency.
>Uh... No? What are you even talking about, barbarians generally wear little or no armor.

6/20, 3/10. I think. But then, the odds of NOT getting a critical in those times looks to be about 74%, so I'm not sure how it works out exactly. I hate probability.
