Randomness of data disks
Ruins the mode. Pure luck on what data disks are given and they change the game mode entirely.

It's been said that all the cards are, in fact, cumulative.
That said, the "leader resolve" card was bugged during the initial normal mode rollout. In that case, the bug was that the Leader Resolve card was improving the stats of ALL allies, not just the leader. If Vader is going after other toons of yours, it's probably that they simply haven't fixed this yet and your other toons are also getting the bonus. If Vader is going after an enemy, I'm surprised, because I'm outracing the enemy easily with Vader, and it doesn't sound like your unmodified speed is less than mine.
