You're actually doing quite well! Excellent
I'd just like to interject a personal viewpoint and hope I can follow your exemplary example:
The PvP players of the game
do have to amass a large amount of materials and resources to build ship(s) survivable against other, carefully considered builds. Even in PvE a 'vanilla' ship soon becomes a liability as NPC's become engineered (not terribly smart - but clever enough to wake out if they take too much damage) so engineering materials will be required also.
The only difference (regarding materials) between the 2 play types is that the PvE player is more likely to amass the materials 'on the go' as the requirement is less urgent.
About the only 'placation' I could offer to the PvP player is to treat the 'needed' grind as a rite of passage into their chosen play style. No criticism or argument about the need, it is obvious - but it should be made clearer to those wishing to pursue this path that to get there the journey will not be a bed of roses
