Wars are not just the large conflicts of the kind you refer to. Take WW2: would you consider sniper mission any less a part of the war than the sea battles, or ground troop conflicts? All of it counts.
The "Star" in the title is more a "science-fictiony" reference, and the fact the story covered several worlds, than the strict concept of space battles between ships.
Your "how big and powerful my ship is" was the point. After we were introduced to regular SDs in A New Hope, in order to illustrate that the Imperials were still a formidable force (even without a Death Star), the Executor slowly cut through space like a neverending threat one could not escape. That worked well in the pursuit of the Falcon.
In Star Wars?? Even ST falls short in that department.
While I agree that the oversaturation of Jedi heroics seemed like Lucas catering to fanwanking over lightsaber duels and "badass" Sith, I appreciated their presense when limited, as in the original trilogy. The Force users were still the game changers of the galaxy, but other characters played a strong part, too (unlike the prequels).
Probably.
