Thanks for the feedback. The use of the multiclass system in 4th edition seemed a natural way to express how we wished to portray nobility in a game world.
I was never satisfied with the various Noble "core" classes of 3.x and initially we thought about feats in combination with our Heraldry system, a modified version of the d20 Modern reputation system (for those looking for it, we had to take down the 3.5 Heraldry product down with accordance of the
GSL).
We still have the Heraldry system for our 4th Edition Feudal Lords setting, but we simplified it how it works. We also added more meat to it (I cannot wait to share exactly how we do noble and royal titles, but we still need to iron out a few kinks).
We also have two more Multiclass Characters in the works, but I will divulge them when they near completion.
