I think missions are fine as it is, its a nice hub of interactions, though everyone was quite excited to this feature and moved his -insert faction here- battleship for some fun. I personally find this mission grind as nice way to dilute usual trading. Although with new reality and "economy balace" from Zoner perspective, as all ores became useless, there's not much left to do as Zoner. So people dusted off their Zoner caps.
