Some great suggestions here, hope the devs will take a look. I never understood why they totally took away the respect in warzones, instead of just fixing the issue.
Just like someone said, I also agree that we should be able to respect only in spawn zones. It's really bad when you queue for a pvp match and your team lacks one or another spec that would help with making the match more even.
An example just out of my head would be a Huttball match where your team lacks a player with some sort of "harpoon" or "force pull" skill and all you have is an infiltration shadow, that could respec into the defense tree to get the force pull...
