Are you eating the pudding?
 

I just tried the test for the new V5 and it is not user friendly. One of the first things any forum user wants to do is set up a forum category or topic and there is not clear path or instruction to do that. The help videos don't look like the test and it is in general not user friendly. I think your programers are so familiar with what they want to do and how they want to do it that they don't think about an end user who might even be setting up a forum for the first time.
