I couldn't agree with you more!
It seemed the only way I was able to finish the Combat challenges was to finish the first two rounds perfectly.
In the first two rounds or even the third if you can, go for these goals.
Variation bonus 5000 - Use all of Batmans combos in one flow
Flawless Freeflow bonus 1000 - Beat a round in one flowing combo
Dark Knight bonus 500 - Beat a round without taking damage
Perfect Knight bonus 5000 - Beat an entire challenge without taking damage
On top of that, go for large combos as that is a super easy way to rack up the points.
