Separate K/d for heroes

Hello, I wanted to suggest different k/d for heroes, and a separate stat for showing number of enemy heroes my troop(excluding my heroes) killed to number of troops who died to heroes.

Heroes seem fairly different than the rest of the troops, can be upgraded, etc so I believe it is only fair it gets treated like one. Letting it affect the stat as it is will ruin the stat dynamic to an extent. Besides, having a different stat for heroes will make a player's profile more clear, while it also expresses their skills and gameplay better.

Hope this will be considered.
