it's split up so u dont get to much of other stats benefits stacked from those main stats. I.e. if u get dex u also get parry and so on and so forth. So to mitigate this, they split up dmg into another column. I dont see the issue. Also, how does it take up a stat slot? It doesn't take up anything. Its a stat. They can make a piece of gear with 10 stat slots if they wanted. It's not using up anything.
