IMO as a controller play, no, I don't think there is.

And I think they've been throwing in smarter solutions to keep the number of buttons down whilst having more abilities to use.

But as somebody who uses the Expanded Crossbars on controller, I feels I still have room for more. Though how much room varies from job to job.

However, I feel like with anything that gets mixed views like this, the true beauty of having multiple jobs per role is that they can satisfy different types of people and what they like.
