Yes, you had crazy durability in the unit, though like I said the unit evaporated once you had danced those wounds onto the unique models.
Looking at the Imperial Knights, an army I just ordered the components for, the gork and morkanaut are in dire need of a point rebalance. A Knight gallant is the same price as a morkanaut at 354. That is absurd. It is an 8/8 with 24 wounds, a 3+ save, a 2+ to hit, and can access 15 titanic foot attacks at S8, AP-1, and D2. On a model moving 12" with a 5+ invulnerable save to shooting. Granted, it has onle a heavy stubber for shooting but its melee options are far superior. 6 extra wounds and a better BS plus 50% more movement.
When you look at the shooting options for knights it only gets worse. Some of the shooting knights are only marginally more expensive.
