Dracri,
I'm sorry that you feel that way about your experience thus far. It does sound like you have gone into your Revit MEP implementation with unrealistic expectations for a product early in its product lifecycle.
We on the product team have talked at length about this subject, I have even blogged about it. Would we like to have a product that does all design and documentation needs for MEP projects of all types and sizes for all countries? Of course. Are we there yet? No. If you think about it, that is a pretty tall order.
Revit MEP is not a drafting product, it is a design and modeling product that assembles a BIM, from which documentation is issued.
Autodesk has a product that does drafting, it's called AutoCAD and it's been on the market for 25 years being the best, most flexible drafting platform available. We also have an MEP-specific product that's focused on drafting and documentation for MEP, AutoCAD MEP. It sounds like that is the focus you are seeking in your software.
From a value perspective, Revit MEP is not sold on its own, only with AutoCAD MEP, so you have a purpose-built drafting solution available to you, should you choose to use it.
I'll take a look at your linked posts. I'm sorry we weren't able to get to both. I spend a great deal of time on the Autodesk and AUGI forums, as well as my blog addressing product capabilities, both good and bad. It's never a situation where we avoid the "painful" stuff, just a matter of time, nothing personal.
Cheers,
