They're not as powerful, but still useful. (You just need more of them
)
The alien cluster will get new content, new modules, specific quests, it will be interesting to explore. Also, SOL might create an outpost there and it will post inter-cluster bulletin board missions
I tried both more and more powerful. Had 15x ADR-1 and they were sh*te, then reverse engineered them into 1x ADR-15, and even *if* it hit, it didn't come close to chasing a 2 m power ship away.
So *that* won't make me visit the AC again. But new content/mods/quests may persuade me ;)
