Aye, its odd how the balances have changed : getting your first SotL was once a badge of progress : it was culmination of months of work and the acquisition of skills and game knowledge. Now I see players of just a few weeks who sail SotL fleets that would once have been considered the prime power fleet of a veteran. My first SotL came off a TW : she was a 48att and she was a terror. How good? Well, she put me top of the win ratios and thats not an easy climb. Now, she would be distinctly average, maybe third slot at best. Even maxed out now, she would still be average and with techs, etc, no great wonder at all. That's a shame for once a ships name meant something in the games lore and history, now, mere numbers or 'Unnamed' suffices for they are all much the same.
The way to create interesting battles between power fleets is to create choices for the owners : more for this means less for that : Stan is right : if both can max them all, both will, eventually, and then its down to chance to decide the winner. So, Stans notion of a higher attribute limit for each sector but maximum attributes per ship being capped so you cant have the perfect maxed out ship is sound. Then the owner must make choices, must make compromises, and in those choices and compromises lies the necessary diversity that creates uncertain outcomes.
Then those who get it right will create names and legends, which we need a bit more of here.
