No, they weren't.Everyone was a caster in 4e.
No, they didn't.The classes worked identically.
All 5e classes have class features. Clearly perfectly identical!They all had "powers."
The system was designed to have a common framework. Next thing, you'll be saying every poet who ever wrote in English is exactly the same because they used the same language! Or that every game ever written in Unity is "uniform" solely because they use the same programming language.The system was designed to be uniform.
"Powers" are literally just...things you do. Claiming they're all spells is absolutely false. Claiming they're all "uniform" simply because they have a standard format is ludicrous.
