He said he played in Year 1 so he had plenty of time to level both Striker and Defender. I started Day 1 and had both sub-classes maxed out with like 3-4 months left until the Taken King dropped to start Year 2. Not that leveling is that hard now, just pay $30 and you can fully max any subclass for the Class you paid the $30 for. (I'm going to do that with my other two Titans and have three maxed out Defenders)
