Trying to create plumbing systems that worked in real world designs took a lot of effort to make work. Especially sloped pipe. A lot of firms used workarounds and created Revit plumbing layouts based off of pipe types or worksets or other means other than by system as Autodesk had intended. It now looks as though firms should rethink these workarounds, and actually create pipe systems based off of real pipe types the way Autodesk intended it to be used. Of course, there are other enhancements to existing tools, and totally new tools and features that were added as well. Even though there are numerous improvements to the software that will make our Revit MEP world a lot easier, we can't open the box, install the software, and just jump into the new version on our next project. One of the disadvantages of a user of MEP, is that we have to follow the architects lead. While there are enhancements in Revit Architecture, the architectural new features aren't as much of a game changer as the new features in Revit MEP. The Revit Architecture software is on it's 25th release in 11 years while Revit MEP is on its 7th release in 5 years. So it isn't as mature as it's architectural big brother. So architects might not see the need to upgrade until maybe June... September... or even next year on their projects. And because project teams should always work in similar Revit build numbers, MEP users might not have the chance to become more productive with the new features until an architect decides to either A) Upgrade an existing project, or B) Start a new project in the new 2012 version.
