I'm picking powers that actually saw play and that I recall seeing play. That was one of two at wills I recall on a "laser cleric" and the one that was more commonly used. So I'm cherry picking by picking what people did in play?
They likely choose that power either because it was powerful or not samey. So by using the foundation of what people actually played with you actually are already sifting to most of the less samey and/or powerful powers. Not surprisingly most of your list is still extradionarily samey for you to have done that.
Oh noes. People attack things and that makes them samey.
Yes. And there ought to be a sufficient level of differentiation to make most things that would be samey be different. This is accomplished in 5e in dramatic ways between the barbarian/rogue/fighter classes. In 4e that differentiation rested the shoulders of push 2 or pull 2 or grant +2 to attack, etc. In 5e that differentiation is Rage/Reckless, Action Surge/Lots of Attacks, Sneak Attack/Cunning Action. 5e's differentiation in how characters play round over round is to a much greater degree than 4e's formulaic differentiation.
Do you believe that the fighter, the rogue, and the barbarian should all be the same class? Because in 3.5 they are far more similar than those powers. So is samey something you consider entirely inherent to D&D?
I didn't get into 3.5e. Can't comment on it.
So ... in combat it's samey if people do damage with their actions? The level you are looking at things makes fireball seem samey to a sword swing. In any edition. They spend an action to do an amount of damage to some number of targets. Indeed there is no additional effect with either fireball or a classic fighter making a sword swing.
If you see a classic fireball as similar to a classic sword swing then I don't see your definition of saminess as meaningful. If on the other hand you do not see a classic fireball as similar to a classic sword swing then I don't think that group are samey.
Now you are zooming out to far. Just like anything you want to call samey I could zoom in so far on that there's nothing samey about it.
I think there are different degrees of differentiation that affects perceptions on sameyness. 5e has a much higher degree of differentiation. It's not that there are a lot of moving parts per class - it's that the difference in those moving parts and other classes moving parts are huge! In 4e there's a lot of fiddly moving parts but the degree of difference between them is much smaller -ie is below the degree of differentiation that I personally find samey.
