are the servers diverse or are there thousands of jedi running around with maybe one or two bounty hunters.
Well 1/2 the classes are force users. I'd say there is a disproportionate amount of jedi/sith but I don't think it's real bad. There are a good amount of Troopers/BH because those are some BAMFs. Not a whole lot of smugglers/IAs but I think that'll change once people see how powerful they are. Sith inquisitors are everywhere in pvp but that's mainly because sages/sorcerers are considered the best pvp class atm. Once a new class is considered more powerful 1/2 of them will switch.
It should even out I think. Each class is pretty unique and interesting.
