I suspect OP is confusing number of attributes with number of abstraction layers.

Attributes are not a problem as long as they're listed with intent and not just thrown into a bucket, and there's some rationale for their existence.

It's much harder to trace flow down and up through multiple abstraction and encapsulation layers. And it's harder still to remember the layers for different classes/applications. And it's even harder to do this when all the class names are related and hard to tell apart.
