I was a bit surprised we were allowed to keep mirrors but at the end of the day that requires you to get into the TC4 chain, and that was kind of the point of TC in this pack: to give you workarounds.Mirrors allow you this too.
Wich other alternitives are there that cost energy? That is not AE
I dunno if any alternatives for long-distance transport off the top of my head, other than galacticraft cargo rockets (which I dunno how to use)
There are options for medium-range item transport, such as drones, robots, item cannons.
