If there were no XP ET would be exactly the same game it is now, except each player on the server would only have their own natural abilities to rely on, rather than be assigned additional abilities by the game simply for being on the server for a certain length of time.
You aren’t assigned anything for being on the server for a certain length of time - you are assigned additional abilities for completing tasks: whether it’s fragging, constructing, healing or supplying. If you do nothing you get nothing. And, with the exception of a 3 star field ops holding an entrance or a medic with adrenaline and 4 star battle sense, I don’t exactly see what the huge advantage is. If you can hit heads and do your job, you’ll catch up.
And besides, not everyone is into playing a head to head test of skills… the vast majority of people just like to run around and frag. They like to gain xp and new abilities. The proof is the simple fact that there are only a handful of servers dedicated to sw/lms/obj. The game means different things to different people. No way is more “right” than the other. I play enough SW during matches - campaign is just mindless fun & practice.
