I gave up reading them. The quality of the book varied too much.
When did you give up?
The initial trilogy was marred by publisher interference, since they wouldn't commit to a trilogy at first too much from the later books was merged with the first, then there wasn't really enough left to make a trilogy but they did anyway.
For me the problem was the end of the Serpentwar saga, It is a failing of some RPG settings that high level magic users become overpowered and boring, and by the end the story was full of them.
Those parts of the books where they were absent were good but when the story centred on them it became dull.
