Heh, this again.
How dare I tell you stuff like "go play some other game"? Well its very simple: This is how this game is! This is how it was designed!
Skyrim was designed with no class system but a number of "perk trees" from which to choose to create your own class. Sure, you can use Destruction as your main offense, and asking for it to be fixed so that this goal is achieved is 100% legit, and I'm backing you 100% on that. It needs to scale.
Yes, how dare you. In fact how dare you expect people to play how you think they should in a game series that's always been about being the character you want and playing how you want.
Asking to be able to ONLY take Destruction and not have to touch any other perk, yet be able to perform as well as someone who uses all their perk points, is not only illogical, it is down-right childish. You are not thinking AT ALL about how that change would affect the current game, you are just obsessed with re-creating a different game.
That's a lot of assumptions in one post. For one thing, you seem to have no concept of TES lore or past TES games. The very lore of magic in the game has included the idea of specialized casters, even concentrating on them, not just the gameplay mechanics. Beyond that, the NPCs and Enemies in Skyrim, guess what? They specialize as well.
As for what you think "I want" ? You're wrong. You confuse want with support. My character has Conjuration, Illusion, Destruction, Alteration, Restoration, Enchanting, Smithing and more as this point. What you're unable to grasp is that I support people that want to, "Play the game in the way they choose, just as EVERY SINGLE PRIOR TES GAME ALLOWED." Skyrim isn't one game. It is a part of a series of games, and thus must absolutely deal with the fallout when they change the long standing mechanics (or contradict the longstanding lore) of everything that has happened prior in the series. People have every right to be disappointed and to complain.
More importantly, it goes well beyond wanting to specialize in a specific school. Certain schools of magic, like destruction, stop. They just stop. They stop entirely. Past a certain point they no longer improve in any way. They do this long before the level cap. A 30+ player will start to see it, a 40+ player will have to grit their teeth through it with overly complex strategies and the 50+ plus players will be tearing their hair out by the time they get to the 60s and eventually hit 70. Why? Because they stop. Melee and Ranged continue to scale all the way up to 70 through a variety of means. Spells though?
Nope.
Certain schools, like conjuration, continue to scale - bound weapons especially because they work hand in hand with melee or ranged scaling. Things like Alteration's Dragonhide will continue to scale because 80% reduction of all damage is always going to be 80% no matter what level you are.
But a fully perked Master spell from destruction? That stops. It just stops. Entirely. You will slowly see one melee hit equating to half a dozen casts of your strongest spell, and by the time you get to the 60s a single melee strike will completely eclipse anything you can throw out. That's not "an intended form of play" that's, "this skill set continues to scale all the way to 70, and these? These over here? They stop. You can get max level spells before you even hit 30 and be fully perked out and that's the most damage you'll ever have unless you switch over to melee or ranged or bound weapons for melee and ranged. It's not just night and day. The amount of damage you can do when comparing a 60+ melee player to a 60+ caster is that the melee player scaled all the way to 60 and will continue to scale to 70. The Caster though? He won't. He stopped scaling entirely back in his 30s, because he was perked out then and he had his master spells then and he's never going to get anything better."
There are a variety of reasons for this, but one of the most important doesn't even have to do with the skills themselves but entirely different skills. Enchanting and Smithing. Guess what the interesting thing is about how enchanting and smithing effect melee and ranged versus how they effect casters?

All of that is meaningless though. What's important is you can't get down off your high horse to realize, it's a single player series of games that have always let you create the character you want, a series with long standing - still canonical - lore that supports specialization and a series that has always allowed specialization. A series that even in Skyrim supports specialization by presenting you with NPCs that specialize. But you? The player? You can't specialize in what you want anymore. Sure some schools like Conjuration can get away with it, but restoration and destruction? Nope. It's especially bad for restoration because it actually used to have damage built into it.
Luckily none of what you think is relevant or valid.
Why?
Because if Bethesda doesn't fix it, then the modding community will.
