Although the death-roller is the single most hated position here in DB, it's actually the secret weapon-skill, that needs an adoption, since the intention it serves in BB (the player can only play a part of the match), is lost here. Of course this has more impact on a more expansive player then a cheap gobo with a chainsaw (for example), but it also tweaks the "bang for the buck" for these other players.
So - in other words - best would be a solution, that brings back the balance to the force, which was broken by the combination of SW and only 1-turn-drives. And the DR is sith lord...
