I noticed a slight buff to some of my stats with today's patch, so I decided to head to the Rift (I'm DC) to test my dps on the mammoths and giants east of Riften.
As a sorc, I was previously able to pull ~1.6k by dropping my mines twice during the fight. Now, the giant's health was so low that it went down before my second set of mines even armed, but my dps was significantly lower.
I also tried the storm atronachs in Craglorn, same deal.
Why were these nerfed? These large mobs are pretty easy to avoid if you don't want to fight them, nor do you have to fight them at any point for a quest. I'm sure I'm not the only one who is annoyed by the inability to get an accurate dps reading without having to have someone heal you while you fight a heavy-hitting boss.
