What was said above, was mostly true and something were untrue. The Sith is simply over powered, many things lead to proof that it is true, examples? IA's and BHs are the biggest ones, and the fact that because so many people knew they were OP they had to make Hutt Ball able to be Sith vs Sith to handle the population. It does need to be nerfed, nothing is mirrored with the classes maybe tid bits are the same but nothing is exactly the same and different animations that they had stated to people who asked back in beta. So whether you want to believe it or not Sith need a big rework and so do Republic so they can at least have some sort of similarities that were mentioned back in beta and before beta.
