I could see a Conquest Omicron being useful in a few circumstances, just not the ones listed so much.
One scenario being an Omicron that decreases the Stamina consumption of a team, for easier climbs through the zones. The other being one that does something similar to JML and lets you get Defeat / Survive feats with plug-and-play characters.
But also, I’m getting to the point where Max Crate is more an investment of time than ingame resources, and I’m not in a TW/TB intensive guild so I don’t know if that changes what becomes worth it.
