Seriously, we've got 3 subclasses without superiority dice. Where does this sudden fear we're going to use superiority dice for every single subclass from now on?
There is none. Just pointing out that
these particular subclasses aren't doing anything mechanically interesting or innovative, because they're just looting BM mechanics. They are using the BM hammer for these subclass nails, and it's not doing the subclasses they're modeling any favors.
So glad you know that the subclasses can't feel like a cavalier or scout without playing them at all, or trying out their features. I look at the pdf, and I see plenty of "charge into combat!" and skirmisher abilities.
But each one requires a resource allocation - a decision of "do I want to spend my dice on this or something else?" I shouldn't be making a tactical decision about charging or not, I should just be charging. Liberate these mechanics from SD (or change the way the SD are restored), and you might get something.
Without referencing the superiority dice at all, can you explain how the cavalier isn't goign to be charging into combat on a mount? Or the scout isn't using stealth and skirmishing? Because that's what they clearly look like they're doing to me.
Why should I avoid referencing SD? Using SD (in the same way as the BM does) is pretty much the core of my criticism. That's the mechanic they're using to do these things. If they don't use that mechanic, they can't do these things much better than any other character, and if the designers didn't use that mechanic, I wouldn't be grousing about them using that mechanic.
It sounds like your complaint is more "Gods sltarn it! I want another simple, mindless Fighter!" Because what you're actually saying doesn't seem to make sense - you're exaggerating things into strawmen and charactures.
Interesting how I'm accused of strawmen and caricatures in a post that claims I can't possibly know what I'm talking about, tries to argue about other things, and wants to put words in my mouth I've never said. It's not like BM manuevers are the only possible expression of a complex fighter in 5e. My opinion of the College of Swords is similar, though you don't seem to take exception there.
I'm really not too worried about providing my opinion on the subclasses presented for me to provide my opinion on, and my opinion is that these seem kind of phoned-in and samey because they take too much from the BM without giving us new things (the new SD mechanics aren't much different from new manuevers, narrowed). You're invited to disagree with me if you feel otherwise. I'm just some dork on a D&D message board, after all.
