To no one unless you have a specific need, although a special case could be made for prismatics and to a much lesser extent the mining lance
For example Prismatics are used extensively in PVP and in very few niche cases of PVE.
So except for PVP, they have little use and if you dont PVP you can skip them entirely and replace them with normal A-rated for general, not-often-in-combat pve usage or for Bi-weaves for the combat oriented types.
The mining lance can be used to poke asteroids at longer ranges, but even so, it has quite some drawbacks.
Everything else is more or less fluff
Yea i know people will say Packhounds, but they are rather nice for the show and not as much for everything else.
Their total damage (assuming that all mini missiles hit the target) is lower than of a seeker, but they have this tendency of setting off each other before hitting the target.
However, if you do intent to pursue them, let's say out of academic interest, keep in mind that:
- there is a weekly tick, on Thursday, that triggers the PowePlay turns (PP is turn based and each turn takes a week to complete)
- you need to stay pledged to a Power for at least 4 weeks to unlock the modules
- you also need to be rank 3 with that power when you reach the 4th week - that is you have to acquire 750 merits in the week before.
- to acquire merits you need to destroy ships pledged to another power in their control systems for 30 merits a ship or to go in a PP Combat Zone and kill highly engineered ships for 10 merits a pop (and nothing else) or to ferry fortification materials - 750ton for a price of 7.5 millions credits if you try to do them at once in a T9 or a Cutter.
All in all, if you ask me - they're not really worth the effort (tho i do have some of them) - at least not in the early phases of the game.
IMO reserve this activity after you really find a use for them.
Your priorities as a new player would be to unlock engineers and the guardian modules (FSD Booster and maybe Guardian Shield Booster, but other modules are useful too)
