"I think to no one's surprise Wraith and Pathfinder are our super-played characters," he said. "And then Gibraltar and Caustic on the other side. As people have seen throughout the season, we've tried to sort of nudge those closer together. For Season 2 we will have another set of balance changes that will….we always strive to make our characters pretty even choices. So it's sort of pick who you want to play who fits your style." – Drew McCoy, lead producer of Apex
