Which class to pick? First post, just trying to get some help with which class to pick. I'm looking to make either an Aran, Evan or Ark for my tera burning character. I've never gone past level 140 with a character but I'm looking to. Out of the 3 which one is the best for getting through all content? I'm looking for something that's above average in mobbing and bossing (doesn't have to be S Tier) and that scales well unfunded that (hopefully) isn't a one skill button masher. Can anyone recommend one?
