One notion that I didn’t include in the list of “significant changes” ideas (posted earlier in the thread), is that of consumable “add-on devices” for ships.
Ships could have 1-3 slots for one-time-use devices, with categories of Offensive, Defensive, or Utility. Generally short-term or limited area affects, device consumed on use.
Something like a small attack frigate might get just a single Offense device, a Logistics Cruiser might get 2 Defensive slots, an Exploration ship like an Astero might get a Universal slot (fits any) and a Utility slot. Larger ships would have all 3 slots with the mix varying by ship purpose.
Offense slots could have effects like rapid fire, bonus tracking, range bonus or lock time. Defense could be resists, warp core strength, capacitor refill, target lock break, etc. Utility could be for speed increases, scan strength, ECM strength, remote boosts etc.
These would all be somewhat expensive relative to their effects (more powerful = more ISK), so they’re not just burned off casually. They could shake up the overly predictable combat meta quite a bit and allow for some new strategies.
A ‘rapid self-destruct’ Utility module would fit right in there, I’d say.
