It is a great mod for people who enjoy building up their character
I suppose.
Personally, if I wanted to see my character grow, I'd play Singleplayer, or maybe cRPG, though I hated that because you get killed by way better equipped people all the time, unless you spend like 3 hours every single day playing
Others like being part of a faction and defending their castle. And I suppose that's where it's at: multiple factions working together.
Of course, you get much better siege action on Native or Invasion, but there you don't have those factions, just A and B
And of course from the RP view...
Well... it blows
I know, I know, "you need to bring the RP to the mod, not wait for it to come" but let me tell you, I have been on many RP servers before, not only from Warband and this is anything but well suited. Especially for people who want to rp and not work for 2 hours to get their equippment, so they can actually look their part
So yeah
Great mod: I guess
For RP: Certainly not
