I agree. While Warband offers some interesting enhancements to native, it's nothing compared to what Sword of Damoclas does to this game.
To be true, it isn't really important if SoD will be ported to Warband or not, the only thing that really matters for me is, that this great mod will be continued =D
I played Warband for 3 hours (with 5 times Laptop overheating and shutdown, but that's another story and will be a matter of the past in a few days, hopefully), and then went back to SoD. It is feels so more complete, challenging and interesting than Warband. Also, the way you can recruit your kingdom units (over baracks and practice ranges) is so damn more logical and interisting. If Warband would have some kind of this unit recuiting system, than it would be more interesting, but as it is now, it's an enhanced native with some little addons and improvemts. Nothing less, but not more either.
The only real cool feature is the multiplayer part.
This feature, however, rocks the house ^^
