Sorcery points can only be spread so far. Also not every Sorcerer is a blaster. I chose Sorcerer as it fit best for my character concept. Why penalize because a player for trying to play a character differently. Other spellcasters, both full and 1/2 casters, have other abilities that make it powerful and have larger selections of spell's known.
Wizards can be blisters and regain spell slots after short rest. That's powerful. Twinning spell's can be very costly. And with a limited pool between long rests, can be depleted very quickly.
BTW my character doesn't have twinning (though have quicken) and no plans on getting it. I have Subtle. Not everyone tries to build the most powerful character.
That's like saying 'my character concept is a fighter who casts spells but EKs suck at spells compared to other casters. Why penalize me just for my character concept?'
Classes are mechanically different from each other on purpose. I prefer for fluff to inform mechanics. For those who don't it is easy enough to refluff other classes to your purpose. Far easier than it is to change the mechanics at any rate.
