I was thinking earlier that a few multistage bosses could be quite interesting to fight as a group.
these multistage bosses would have certain objectives that you would need to clear inorder to move to the next stage.
You'd still be able to disable the boss in the first stage if you so chose, but with each objective cleared, your potential rewards would be more diverse.
(random npc boss formulated to demonstrate the idea)
Crimson Operations Base
Rank 650 Rare Boss (12 person)
Share Range 250-1000
Hull - 1,500,000
Shields - 800,000
Attack - (Rank Matched to the attacker/is not sure can be done?)
Defense - (Same as before)
Stage one - Have 10 people use emp spheres to 'dampen' the base shield grid. for each of the 10 emps on the base, you deal 3% of attack damage to the hull even while the shields are up. Reward for disable in this stage is a weapon module with an activated ability (12 hour cooldown) that allows 2% of attack damage to bypass shields (regardless of target, be it npc, player or base), limited to two per ship. Or a shield module that reduces the effectiveness of emp sphere on your ship by 3%
Stage two - Have 2 people use Recondite Intruders on the base to disable the base weapon systems for a short time(1-2 minute duration) Reward for disable in this stage would be a module or planet structure that granted a constant buff that reduced disarming bomb/orbital mass disruptor's effect by 3%
Stage three - Target's defence falls by half but attack increases by 50%. Reward for this stage would be a module with an activated ability that boosts attack by 25%, but reduces defense by 25% with a potential for overload/backfiring. if an overload occurs, a random researched attack or defence module is broken. if backfiring occurs, take 15% of the damage you would have dealt to the enemy, on rare occasions it will kill a T.O
Welp, feel free to tear my idea to shreads~

tweak as needed, I suggested this because it'd make things more interesting rather than 'who can click fastest and has higher attack/energy'
