M8 I recommend you to pick a class you think gonna like or pick something you think its cool play it allot gear it and learn it by 1v1ing allot
This to be honest. If you're new to the game, you might as well pick the class that you like the most, since you're not likely to be better at a specific class. Every class has plenty of potential if you learn it well, but then, learning it well is easier said than done.
