Install a "Taunt" mod, so your spell will bypass physical armor (because an insult thrown at the mother of your enemy should NOT BOUNCE OFF HIS PHYSICAL ARMOR)
As for retribution, I think it's not that good for a team build : you need a lot of points into it to be worth it, and even with full points, enemies will still focus a lot the other members of your team. If you cc your enemies, they will not focus anyone, so retribution is useless in this case too.
Retribution should be ok on a LW character, for fun, but in a team ? I don't know really.
