I rather liked the Empire series, where he wasn't as hamstrung by his source material. It helped that Janny Wurts was along to keep him from going too far astray.
The problem, Goober, is that Feist wrote most of the Krondor books more laundry list: event-event-event-event-event-event. The narrative structure took back seat to trying to pack all the events in. While this can be exciting in and of itself, the importance of those events is lost. If I had to compare it to anything, I would point at Moorcock's Elric of Melnibone and the like.
Contrast that to something like, say, The Lord of the Rings or George R. R. Martin's A Song of Fire and Ice. We have long chains of events in both series, but at all times, the narrative structure bolsters and reinforces the central themes of the stories and knits those events solidly into the story core.
Don't get me wrong: I liked the Krondor and Empire books, and read everything up to Rise of a Merchant Prince.
