its a good point, a commando, played well, should be able to kill a jedi, most of the time, of course if they insist on standing there and letting themselves get hit, the lose rate will be 100 percent :D
rather than getting rid of jedi, i would rather see the return of 'visibility' and the consequences of visibility, be a reason to be a bounty hunter again too.
Personally, i'd get rid of officers, their a useless support class, instead i'd replace them with a Ranger class, the Officer skills etc, would be better off as a expertise set, much like beastmaster, that anyone could take, or better still faction expertise, gain faction points and 'level up' in faction, gaining expertise in officer as you do, it would make more sense and give pvp'ers another reason to actually pvp.
