Totes hijacking Earl's thread, because Sectorials.
Corregidor sectorial. (Cor-reg-i-dor?)
I lose out on a bunch of stuff, including Hacking Device Plus/Interventors. I gain some good things like Link Teams and bonus AVA to TAGs.
Is the list worth it, or is vanilla Nomads better?
Link Teams seem pretty awesome. But losing out on super sweet hacking seems like an iffy price to pay.
If I haven't made it clear before I'm relatively new to the game, but I've been following it long enough to know that Interventors are a pretty new unit for the Nomads, and that they were considered the Hacking Faction well before those Interventor rules were released.
From what I can tell with the Corregidor Sectional you lose out on some of the best Hackers in the game, but that's not to say the remaining choices are no good. Just from a quick glance it seems to me that a Wildcat Hacker would be your next best choice, although even just a cheap Aguacil would probably be fine if you plan to keep him back and either use him defensively, or use the Nomads plentiful supply of repeaters (IIRC) to affect the battlefield.
As for whether the Sectorial is better or worse than the Vanilla list, I'm not really experienced enough to say for sure. But AFAIK the two lists seem to offer enough advantages over the other for one not to be an auto-take over the other.
