Having trouble finding a fun class

I've always found it pretty easy to find a class I click with on the previous games, if not enjoying all of them.

Maybe I'm just not looking deep enough but it seems like the classes are just a little lack luster compared to the other games. They seem a little underwhelming.

Anyone else feeling the same. I've played an hour or two on each character and it just feels like they are all the same. The only action I found myself using a lot was the fire punch
