-With fleet officer coming, you will be able to pass focus token around. Also, Vader with Squad Leader can turn Lorrir into a beast by allowing him to do his fancy barrel roll at PS9.
I think you're right about Fleet Officer helping him out. Fleet Officer should also help buff Kir Kanos and, really, add a much needed element to the Imperial fleet. A thematic card, but also tactically necessary. Vader + Squad Leader can buff Lorrir, but I don't know if that's a good return on investment. Vader is really expensive and without Outmaneuver or Predator he can have a hard time doing the damage needed to stay in the game. The slight buff to Lorrir isn't enough, IMO, to overcome the gap.
So I agree that Lorrir can be the unassuming surprise attacker. However, I had bad luck running him alongside Soontir Fel, Royal Guard+PtL, and "Backstabber." Next to those guys, Lorrir is the obvious first target because 1) he costs more than "Backstabber" and 2) he is easier to kill than the other interceptors. It was kind of a bummer. So I switched to "Fel's Wrath" for that squad.
A squad that I've REALLY enjoyed, even though I lose about as much as I win, is 3 Alpha's alongside Lt. Lorrir and "Fel's Wrath" 100 points. You send "Fel's Wrath" right up to the opposing forces escorted by two Alphas if there are high PS ships, and hold Lorrir back until the higher PS pilots have been dealt with. Then the Lieutenant can mop up. He is dangerously good against generic B-wings and X-wings.
I like the looks of that second squad, though I instinctively veer away from "Fel's Wrath." For the same cost, why not a RGI + VI? You lose the sacrificial nature of the ship, but isn't PS8 more valuable?
I'm gonna add one more thing. I love Lt. Lorrir. One of my favorite TIE interceptor pilots. But the meta is just terrible for him now. The power of the Engine Upgrade Han Solo has been brought to light (which is so thematic really), and now we have the HLC-toting Outrider and the brand new VT-49 Decimator. It's a really bad time to be an interceptor that repositions without an action. As much as I want to use him in this next TC Vassal tournament, it's just not happening.
Yes, this is a huge issue. Lorrir is still a beast one on one against small base ships, but just can't handle the heat of a full engagement or these large ships.
