Ok the big ass bomb missle I get...it sucks but Ill accept losing a ship in a miserable death...but the MIRV one is *** ***...i mean im all for playing the game but I would love to play the game...it launches so many missles it killed half my fleet.....doesnt help that those missles go across the battlefield....I would say to get rid of that missile...also the missile should not be trying to ram me...as much as that is ineffective after it is done killing half my fleet. Another issue is getting this faction to like me in vanilla is absurd...I dont even think they give out bounties so its so slow to be able to afford the things i need....leaving me to fight fleets double my size all the time because I keep chanting " I have money...I HAVE MONEY" at their station but unable to buy anything...I still need to figure out what commissioning is done but I am not even CLOSE to that
I'm not 100% sure but i think you can donate money to the "foundation representative" to boost relationship (you can find it in the same place where you can find mission postings/mercenary officers).
Also, commissioning means that you pretty much a corsair (a state-sponsored pirate/buccaneer/privateer more or less) for that faction, you first need to be at least favorable with the faction (or friendly i don't remember) and once you accept the commission you get money and relationship for every ship you kill that belong to a enemy's faction fleet (i.e. blackrock hates hegemony, get a commission from blackrock, get paid for blowing up hegemony ships), plus you get access to the best military ships of that faction.
That or agents.
For the MIRV missile thing i'd suggest to first bring in big ships (cruisers and bigger) with lots of PD to tank the volley and then bring in anything smaller once it has expended it's payload
For the BIG missile i'd suggest to bring only one fast ship, kite and hope you can catch a enemy ship or two in the blast. I guess
