Re: Planetside fighting:
In lore the Corsairs were abandoning Yaren, Nauru and Delta in order to (most likely) focus their efforts on fighting the Hessians in the Omegas. A planetary war for them would have been pointless, hence why the taking on Nauru is seen more as an exterminiation of the previous settlers (that hadn't jumped at the chance to leave the planet already) rather than there being any sort of war. There actually is a thread documenting the (BHG) Core's exploits on Nauru, and the Corsair official fations at the time as far as we know where aware of this RP and this was all done with the devs at the time on board too. In all honesty the Delta storyline events were pretty silly and were only done to make some activity and help promote Order activity in the lower Omicrons. From a lore pov though they make almost zero sense.
Re: Iridium:
What more is there to say? The Zoners went hostile to The Core, so they won't have any more Iridium delivered to Freeport 11. That's pretty much it. There doesn't need to be any extravagant forum threads or roleplay regarding the sellpoint adjustment. It's just a logical, reasonable, change and conclusion due to recent events.
