The latest hotfix from Bungie for Destiny (184.108.40.206), among other things, nerfs auto rifles slightly while boosting the effectiveness of scout rifles, and alters the Templar encounter in the high-level Vault of Glass raid.
The patch also provides a few minor tweaks to perks and the Vex Mythoclast and Pocket Infinity exotic weapons. Quick weapon swapping should now be a little smoother as well, among other little fixes. The developer is hard at work on a more substantial update that will address general issues of class balance and underperforming exotic equipment. You can read the detailed patch notes over at Bungie’s blog.
