Wow,  what a crummy and disappointing write up. For mike creative use of a spell is using web to stop movement? That's not creative, that's just what the spell is for. Mike obviously is letting his bias against spell casters and favoritism for the fighter get through here. Somebody in corporate needs to notice that mike is alienating a goods section of the dnd fan base. Fighters and rogues got awesome writes about what they do in "myth and legend" and wizards get this crap? It's even worse than the clerics write up. I like clerics a and wizards, if mike dosnt like cleric and wizards this game is not for me then.

Yeah, now that I’ve re-read that list of solutions, all of them are just bad. They don’t get to the heart of the problem: unbalanced spell interactions. None of those design solutions address the crux of the issue. Instead of penalizing the class at the corners, try tackling the real problem head on. You could limit unwanted interactions simply by saying that only one form of magic (or spell) can affect a target at a time, not more. Does it wreck the fun of creating combos? Yes. But it doesn’t otherwise deflower a class.

First off, going back to spell preparation is already a deal breaker for me  if that's the core idea. I'll say it again - Vancian magic is nostalgia. Nostalgia doesn't make bad mechanics good. But I will comment further.
Cantrips as At-Will - Fine. No issues here.

Keep Spells Under Control - Common sense, but let's face it - players will always find combos that we never saw coming, and there's always a way to break the rules, but this is still a good plan here.

Reducing Total Spell Slots: I'm not 100% certain if this is needed. Since we have no idea how spells work as of yet, this leaves me with very mixed feelings. Could be good or bad.

Spells Don't Automatically Scale: Had that in 4E, glad to see it continue in 5E. But I need to remark on the it scales if you put it into a higher slot. This is not a bad idea at all - as long as spell preparation is NOT the default rule. Honestly, this is sharpie territory for me here. I'd rather see the 3E Sorcerer as the Wizard AND use this option. Only the Dying Earth novels, D&D, and D&D novels have ever had a wizard who had to memorize spells and could actually somehow run out of them because he couldn't remember them. That's not my idea of a wizard. Major wizards in fantasy don't run of out spells or have to stop because they can't remember them. Only in D&D and Dying Earth did this even exist. Spell preparation (aka Vancian magic) doesn't belong in this game anymore. Just let it go. Casting spells through higher slots has a LOT of merit. Preparing them ahead of time doesn't. Seriously, spell preparation rules will get blacked out with a sharpie in my copy.

Keep Magic Items Under Control - I see a lot of good here. Quite a bit of good, really. Simple line - Wand - Yes or No is good. Losing a slot for scrolls? Don't know. Negates UMD, which could be bad.

Keep Buffs Under Control - Again, common sense.

Creativity, Not Dominace - Yes. I like that quite a bit.
