The OP says sensor slot. You mean system slot. All right.
A ship with one attack and access to AC will always use one. Always. That's not good.
I disagree, in that if there are other options for a ship in a support role, which I envision for the TIE scout.
FFG envisioned the B-Wing as a bomber/ordnance carrier. It ended up replacing the X-Wing as a jouster.
The scout would have a poor maneuver dial, it is not a fast or agile dogfighter. It is meant to be a cheap support craft, with the right upgrades harrassing the enemy, rather than being offensive.
If it's cheap, AC becomes even more attractive.
