That's complete nonsense. 4th edition Dark Eye essentially has freeform character building, or something very close to it, and more attributes and skill choices than D&D.
D&D has a very rigid class structure that doesn't allow for 1/4th the build diversity of Dark Eye. Pease stop talking out your ass.
I'll just take your word for it since I don't know TDE well enough, but I'll say that I like when classes are distinct, as long as the options within each class are plentiful.
