I agree this takes a lot of time especially if you completely customize your keyboard with bindings for each character like I do.

I think it would be really cool if they implemented a pet class. For example they could make a Jedi Spirit Caller, and Sith Diabolist. Have the new pet classes be able to summon 1 combat pet at a time that fights with you and your current companion. There could be different kinds of pets Rdps or Mdps. Another Idea is to make a new support class like a bard type of class. This class could have a dps spec, and 2 support spec trees one that enhances and helps heals and another that enhances and helps dps. This could be very useful in groups.
