On the contrary, real combat is much more visceral than what we see here. Have you ever spilled a 2 liter bottle of soda on the floor? It spreads quite a lot and makes a huge mess. Hacking someone's body apart makes a huge mess, much bigger than anything we see in the game. So I say keep it as it is; it's excusable for realism, doesn't LOOK real enough to be sickening, and has a purpose in a core component of the game's mechanics.
I personally like how it is right now.
