Hello, this idea is coming from an empire player but of course these same ideas are all applicable to republic side, esp. because of the class mirroring
I thought that since some of us are Darths, some are Agents etc...it would be a very cool story/roleplaying feature if certain npc's would react to you.
Sith acolytes etc should bow/cower in fear once you get your Darth Title
Imperial military should salute the agents
And bounty hunters should have some sort of reaction when they enter cantinas and other public places, such as people whispering to each other, looking suspeciusly at the BH etc...
These things would make you "feel" much more powerfull once you hit 50 and get the final title, and again should help you feel much more immersed.
