i get a lot of exp, and help my team by usually going with operative class. disguising yourself to sneak pass enemies to spot them out for your team, spot out mines, take their own mg nest and rain down on them, throw caltrops on the enemy team as they try to get to the objective, sneaking to wards enemy turrets and turning them on their owners, controlling friendly turrets to make them more useful, and using com hack make the operative one of the most, or even the most important member of team he can turn the battle in the whole other direction if you know how to use an operative. works good as a light character.
The operative is the most useful class in y opinion.
