Yes, most definitely. This is one of the BIG weaknesses of VW.
All the main competitors of VW (AutoCAD, Revit, etc....) all have more to offer for basic landscaping design. As the distinctions between an architect, landscape architect, designer, etc... are becoming more and more irrelevant, the tools need to adapt as well.
It may be that by stretching VW into separate products
( Architect, Landmark, Designer....) weakens the program overall.
I think if Nemetschek purchased Sketchup and integrated it into VWs - those other PC programs that EVERYBODY else uses couldn't come close....
