I agree. I think it would be stupid to sign any moderately complex agreement without a lawyer having been through it, and having informed you about what you are signing. (I certainly wouldn't sign that.) I also think it would be stupid to have a moderately complex agreement that was not drafted very clearly. And if things go south, you definitely need competent legal counsel.

My entire point was that lawyers like to inject themselves into the process of negotiation, often feel like they are generating value, but in reality tend to generate billable hours and negative client value at the same time.
