Besides, almost every single post here disagrees with you. They bring up the same points I do and disagree with your opinion that the classes are too similar.
Just as I said about making classes too distinct.
What I said about classes already having a lot of difference.
Same thing.
Same thing.
Same thing.
Sorry, but while giving classes new abilities would be fun, I don't agree on the premise of giving them too much uniqueness (with the reasons I stated before). I also don't agree that the classes are very similar right now, as does almost everyone else in this thread.
