First off, i think every class has its own potentional, and i tend to have about the same XP out of every class (slightly dependant on the map and team players)
secondly, there are only 20 lvls and personally i think a person, whos lvl 1, with more skill than abilities will come out on top of the lvl 20 with all abilities.
The only one that doesn't really have the same potential as a medic is the operative class but not a lot of people use that class so don't complain.
lol at this statement, yes i think if you quickly look at all classes, there seems to be less obvious things to do for the operative,
yet trying the class out for myself for a few hours, i quickly realized its not all about the primary objectives, like most seem to think.
i started thinking out of the box, and quickly found numerous ways to aid the entire team, even without obvious buffs.
I currently mainly use 3 skills as my ultimate xp gatherer:
After finding a good vantage point i use HOMING BEACON to highlight the enemies, this gives an quick & easy 50xp per highlight and the entire team can see the enemy even through walls, this gives a great oppertunity to avoid danger and flank the other team.
after the threat it disabled, i quickly rush in to use COMMS HACK, giving me around 30xp and highlighten ALL enemies on the map,
yet another great way to find flanking routes and give the entire team an advantage on both attack and defence.
for my last skill i obviously use the disguise, another quicky xp boost, and a nice way to sneak around almost unnoticed, being able to go where no other classes can and hit the enemy where it hurts the most. also i nice note, if you find alot of dead bodies around (ussualy around chokepoints) you can just disguise as 1 player, undo the disguise and disguise yourself as another body, and so on. this quickly gives a massive amount of xp. :ph34r:
