The main problem was that Chaos Bolt ignored resilience. When one class (spec even) can get around the major stat that is supposed to let characters live longer in PvP with a heavy hitter like this, you're bound to have problems.
We didn't want to nerf the burst damage because it was finally hitting for a reasonable amount. But it didn't feel fair to have it ignore resilience. The other damage reducers didn't feel like a big problem either way. It still ignores resistance and absorptions, which is technically all the tooltip said in the first place.
EDIT: As it turns out, Chaos Bolt does NOT ignore resilience. When the developers went to make this change, they found out that the resilience bypassing was just a myth. They still thought making the change to have CB not bypass other damage reduction affects was an appropriate change. I try to stay on top of all of the changes my team makes, but it's a big game and we typically make a lot of changes every day. The mistake was mine, and I do apologize for any confusion.
TLDR: The 3.1.3 change remains, but resilience is not (and never has been) affected.
