This might have been fixed since I last looked at this, and may or may not be related to the thread.

One thing I want them to fix is letting us see our DOT damage when we have other people's damage numbers disabled. It's so weird that if I place Dia on an enemy, I can't see the damage of it whenever it ticks. Maybe it's because the DOT is counted as a separate "source" of damage or something, but either way it seems silly that it hides the damage numbers
