Ok, other than providing a new method of showing people the moves in MK:D and satisfying the "I wanna be in Mortal Kombat" people, I think Konquest will serve a much greater purpose in the MK universe, and that is satisfying once and for all the storylines behind particular characters.

As Steve Beran said at E3, EVERY character will be in Konquest. In this, they have massive potential in terms of building storylines, and plugging gaps in the plot.

Shujinko, no doubt will have to go to blah's hideout/house/cave/whatever to seek this piece of semprini so that yaka can do yeah, at least once in Konquest. So in this, we have Shujinko fulfilling an important part of the storyline, as well as seeking out another character and learning about them.

Hopefully, this will be the case and that the plotline behind a lot of these characters (eg Blaze, Kai, Reiko) can be put in concrete once and for all.
