The march order would be correct... for a dungeon. We are in the wild and things won't come only foward, they can come around us and we are not forced to have one single line where the paladin will have to waste time to get in front, won't be able to open with his breath. Even Angel might have difficulty to place her powers if we falls on goblin too far away.
I think Mal configuration is better (he will write down soon his tactic, so I'll leave him the honor as he is teh one who has thought about it)
But tacticly talking, if we have to walk in line, I would not put a ranged rogue in second, I would rather put a melee guy in second to support the guy in front if needed. So either Aelek or Tesalyn.
