i propose that we differentiate between Dark Phase engines and Dark Thrusters. Up until the dark command nexus we have been able to get dark thrusters, complex dark thrusters, and then... dark phase engines? i think we should have a limit of 4 dark thrusters and 4 dark engines. the dark phase engine sounds like a dampener anyway.

perhapse we can add in another NPC that drops a third tier of dark thrusters? right now i have 2 phase engines and 2 complex thrusters on my ship, and i hate to see the thrusters go because they look so cool. especially when paired with a dark phase engine. This can even be an advanced tier of NPC that becomes available at rank 600 and is available to rank 2500. enough players are reaching this tier of play that it may be time to consider some new NPCs for this range.
