I love the integration between singleplayer and multiplayer in Mordheim. I am hoping that in the end, if not possible now or at launch, the arena in DOS2 can be as significant. Playing arena matches - if well structured - can significantly increase the lifespan of this game and attract more players. It doesn't need to divert their focus from the main campaign. I agree that now the main campaign should be the priority, but I disagree that even the main campaign can be classified as singleplayer (I mostly play it coop anyway).
Ideally you should be able to import your own characters in the arena. Again, look into Mordheim if you want to have a concrete example. I spent so much time in the singleplayer portion of Mordheim mostly to level up my squad and refine my strategies. So much fun.
With DOS 2 engine and mechanics, it would even be so much better than Mordheim. Just a(nother) suggestion.
