TIEs are minions
AoR page 409, EotE page 389:
Minions are typically not real threats when encountered alone…Minions will rarely be more than a minor obstacle to most parties of Player Characters, a delaying tactic that can stand in the way of achieving a goal that a more powerful enemy wishes to see prevented. Minions also tend to have lower wound thresholds than other NPCs, making it very likely that they'll drop in one or two hits.
That sounds like the definition of a TIE fighter.
- No real threat when encountered alone? Check
- A minor obstacle? Check
- Drop in one or two hits? Check
Also, they TIE pilot is specifically called out as a minion. The TIE doesn't change that; it is, after all, just another piece of equipment. Stormtroopers don't cease to be minions when you give them better weapons, and the same goes for TIE pilots.
