I think Frontier need to spend more time planning their CG's; if they had, they'd likely have seen that combat pilots are being marginalised in this CG.
The focus on this CG is attaining materials in order to build an "anti-EMP" device; which in itself isn't a bad idea as we've had trader-only CG's and combat-only CG's since forever. But one of the materials in this CG required is the Thargoid Cyclops Tissue Samples, which can (to my knowledge) only be obtained by violating a Thargoid vessel; considering traders are not normally equipped to deal with a normal Cmdr, let alone a Thargoid ship; this commodity falls (predominantly) within the combat pilot's jurisdiction.
The issue here is that whilst a trader can putter about the bubble <200ly from Sol looking for the easily obtainable market-commodities; the combat pilot wishing to partake would have to slump off all the way to the Pleiades (or there about); kill a bunch of aliens, then slump all the way back again.
This, I believe, is a monumental waste of time; and highly discouraging to pilots who want to take part, but don't want to trade (and, to be fair, they really don't have to; nobody should be forced to do something they don't want to do).
A better option, IMHO, would have been to make two CG's that are trying to achieve the same goal; the anti-EMP weapons.
One CG is in the bubble, expecting Coltan and Beryllium; the other is in the Pleiades expecting only the Thargoid Cyclops Tissue.
The tiers for each CG should be different and cater for the demographics of the participants; traders vs pilots.
Side note: The two CG's could have been linked by having traders shuffle the Samples from a station in the Pleiades to a station in the bubble; with the threat of Thargoids attacking them (enter CG combat pilot defenders).
