To my knowledge, they’ve never really updated the endeavor list.
Difficult ones are a pain but not bad, per se. But there are some that are disruptive. I’m thinking of Dewan Arthropods and Gorn making it hard to actually run missions on Nimbus III - I’d maybe remove the 120 Arthropods tier from that at least, and expand Gorn to include non-Nimbus mobs.
I’d also add in more variety on the TFO objectives. We only get Borg, Iconian, Lukari and Competitive. It would be nice to have some of the other groups in rotation for variety. Likewise more enemy factions on the hit list.
It might also be fun to have a top tier option to complete a mission from a certain arc that doesn’t get replayed much.
REMOVE: For personal? “Defeat Hur’q Attendants” due to the niche setting to complete it, maybe the “Deal X Damage” (at least in space) ones as I’m not an alt-oholic.
For universal? “Defeat V-Rex”, not that it’s bad per se, but most people will camp those. Also “Complete a PvP Match” Anything else is good IMHO.
Edit: Also Remove the “Defeat Voth Ships (Dyson Sphere)” as that is practically the same as “Defeat Voth Ships”
ADD: For personal? Add more “Complete X TFOs” like Elachi/Romulan, Terran, or Delta (like you said). Maybe a “gain x dilithium ore”, but I don’t know about that one.
For universal? Add back the “Battle of the Binary Stars” one. Maybe add a “Play x Mission” Endeavor, although that may be a little long (wrote that without even reading the bottom line, but yeah it is a really good idea).
It might also be fun to have a top tier option to complete a mission from a certain arc that doesn’t get replayed much.
I would love something like this.
