I think it would be cool if every characters arcade ladder is different, with the fighters pitted against their worst enemies in the MK tournament (like DOA3). Maybe they start off the tournament 'sparring' with friends and then fighting enemies and then fighting the guy that the kombatant hates the most (but they always end with a fight against the dragon king). For example, Sub Zero would begin sparring with Smoke and would go on to fight with Scorpion. Sektor would shortly follow and then the tournament would end with Sub fighting Frost and the the Dragon King. What do y'all think?
