There are a lot of fun and interesting ideas that could be used, but as long as people demand that everything be perfectly balanced with one another things will never change. The reason why most classes of every role feel so similar to each other is because nothing can have a true strength that another does not. I like a lot of the new stuff AST got in shadowbringers, but I wish the cards would have just been removed completely at this point. I liked that the old cards had tangible effects outside of "number get bigger" even if it was only minor. They're just not fun to use as they are.
