I had thousands last DLC but rerolling solved that. This DLC I think I started in the 500's but that quickly dwindled. Exotics are 10 WP a level up=around 40-50 to complete a y2 exotic. And infusion is 10WP per go. Not saying its impossible to go positive. But you've either got to be lucky (I seem to get way more armor engrams than weapon), hardcore player (raids and hours of time), or just dont have anything you need. Edit: Its 30 to fully upgrade Y2 exotic... Sorry was getting my year1's+2's mixed.
