Should I watch season 4?

Im almost halfway through S3, but Im starting to watch House a lot less often because I want to enjoy this season more (Cameron looks the best in this season dont blame me man), I know all the spoilers for the later seasons but thats not the point. The point is that ive heard that the original cast randomly gets fired and replaced by random ass people, theyre probably good characters but im too used to the original characters. Should I watch Season 4?
