We need systems that bring gameplay, we need more things to do when we log in DU and not just handling timers.
Players should never see the end game coming or they will lost interests.
Schematic system is just boring in its actual form. I would prefer having original chematics where we can make researches (material and time efficiency) and copies. The original schematics could be acquired with reward points acquired by other systems such explorations, achievements, PVE, PVP, etc. As example, having a fully researched basic space engine schematic allow you to upgrade the tier to uncommon at the cost of the researches done on the schematic.
Bring some fast-past action with PVE in space but also on ground. Build alien "space dungeon stations" where people can scan and doing in group. Same things can be added on planet/moon ground, procedural buildings to destroy with tanks and artilleries.
fyi, hauling missions isnt that fun.
