It's basically the first time we see a Klingon fleet fight. So it could be argued to be the way they always fight, exotic things like raiding flotillas of battle cruisers notwithstanding.
"Way of the Warrior" certainly had them in the thick of things, being as spearheadish and vanguardish as physically possible. Their lesser showing in "Sacrifice of Angels" might be simply because they were left far behind when the large combatants rushed to aid the sissy Federation forces at maximum warp.
What would have been easier to add to that engagement: twelve more runabouts, or three more Galaxy class starships?
The best way to go might have been to remove all the runabouts. They were the reason the Odyssey
was stuck with fighting at impulse to begin with!
