Let's Revisit the Scoring System:

[maximus__]

More 10-10s would have way too many draws

A draw is better than a loss for a fighter. It makes people have more reason to open up a bit and take some risks leading to more potential finishes both ways.
Nothing is perfect though.

Nothing will change while the gangsters run the outfit.
And i am not talking about the big pink Goofpotomus.

They need to score more 10-8s, 10-7s, 10-6s and even 10-5s. There are not enough rounds for the boxing system to work. A very close win should be 10-9 (Conor vs Khabib round 3). A pretty clear win should be 10-8 (GSP vs Penn round 1). A very clear round should be 10-7 (Jones vs Smith round 1), a dominate round should be 10-6 (Chael vs Anderson rounds 1-4)) and a one sided beating should be 10-5 (Frankie vs Gray 2/3 round 1)

Your criteria is all off. Jones/Smith round 1 was much closer than Conor/Khabib round 3.

 

[Fluffernutter]

10-10 close round where neither fighter had a clear edge.

10-9 one fighter had a better round than their opponent.

10-8 one fighter had a dominant round.

There is nothing wrong with the scoring. The issues are judges afraid to give 10-10 and 10-8 rounds.
