What if bosses had more effect abilites? But rather than just -25% defense or attack they did a few other things.
1)Lower percentages, a bit more often that stack.
2)Non attack and defense related effects IE cloak and Scan
3)Combined effects from multiple effects creating a new effect.

Here's the idea as I see it.

Styrll "destroyer"
Scanner Block, Weapons Damper, Gravity trap

Pulsed Scan Blocker reduces scan by 5% stacks up to 5 times.
Negative Weapons Damper reduces attack by 7% stacks up to 5 times.
Gravity damper on its own only does 3% defense reduction stacks up to 10 times, but if either Scan block or Weapons damper is on the ship then the player ship takes damage base 100 multiplied by the number of stacked effects. This includes the number of stacked gravity traps, but does not on its own trigger the effect.

Thoughts?
