So people may cry about these, however it’s actually a good idea.
For one, it combats botting in FW because the fleets lock quickly and tend to catch alot of the bots, meaning less bot menace. Plus it also makes lowsec pirate groups cry like little girls (see here: Stop the idiotic lowsec instalocking camps) which is always a bonus.
However I think CCP could do more with this, and make it a thing that is implemented deeper into FW.
What I suggest:
Get rid of the current FW missions, I think most FW dudes would agree they’re far to farmable and require no real commitment (anyone and their mother could just drop an alt into FW to farm these). To replace them however, make the current FW NPC fleets payout a fairly decent amount of LP, aswell as making different types of fleets consisting of different numbers, different ship types, maybe make them randomly attack citadels in the area owned by enemy militias (especially low power ones).
Alongside this, maybe make it possible to request aid from an NPC fleet, so for example you can pay 200K LP for one of the NPC fleets to come to a specified system/area with a small frigate fleet with the purpose of shooting stuff or helping with firepower on an Ihub, then ofc a LOT more LP for bigger fleets, with a cooldown. So for example you can only request aid from an NPC fleet once every 72 hours.
The cooldown timer would make them much harder to spam, however another measure to prevent reliance on them or spam in general, is make it so there is only 3-4 or so NPC fleets roaming around the warzone at any one time, and take 24 hours (or downtime) to respawn. So in addition to only being a certain amount, and a cooldown etc. you’d need to try track down where the fleet you want is to try and pay LP to them etc.
Obviously for something like this to be considered the specifics would need to be discussed in great detail, I in no way would want to this to be a thing you could just throw lots of LP at to deal with your problems, but I think it’d be a great tool for FW alliances to be able to utilise (for a high cost bare in mind) to help with operations in the warzone.
