Yes, because it’s a community forum so mostly players are posting here. The only reference to direct damage by SG staff I was able to find are release notes for v20:
- Natalya: Damage over time increased from 700 to 752.
- Kadilen: Direct damage increased from 170% to 190%.
- Valeria: Direct damage increased from 155% to 235%.
Here you also have distinction between direct damage for most of the heroes and damage over time for Natalya. Also direct damage increase for Valeria references the amount of damage she deals with her special skill instantly, in opposition to her DoT.
