What is the best EPT for one or two aggressor lists? I have B and D in mind with ATs, Adv Sensors, HLC and mangler, title

So far I've narrowed them to VI, PTL, or Predator

VI: better for mirror matches and arc dodgers. Maximizes maneuverability and I could afford dampeners, and HLC on both.

PTL: good overall pick for most squads. I like the versatility of choosing full defense or offense actions as needed. Suffers against stress squads.

Predator: Re-rolls to make sure I hit allowing me to mostly focus for defense or offense.

I tried playing an IG squad for the first time last night and I see how awesome they are.

Predator. Best defense is a good offense. Predator insures you always have a way to manipulate offensive dice. VI is a waste of an EPT slot. The IG is not an Interceptor, nor should it be flown like one. Which brings me to PTL. I don't like leaving stress on ships in the current meta. PTL with adv. Sensors it's a costly but effective way around this.

Even in Dual IG2K lists, I try to make sure each aggressor is a monster on it's own. You want to pick a EPT that synergizes with what your droid's pilot ability lets you do.

For example, B has an amazingly offensive, no-action-required ability that helps ensure damage dice rolled means damage dealt. I normally pair him with Sensor Jammer to make him more defensive, Predator or Lone Wolf to maximize his shots not needing actions to hit, and primarily boost or evade as actions while flying him.

C, meanwhile, is all about action economy, granting a free evade while you boost. Push the Limit does well on him, giving you a third action to help you land your one shot per round (again, assuming he's on his own), a Heavy Laser Cannon to toss as many dice as possible at all ranges, Advanced Sensors lets you boost, get the free evade, focus, then do one of your many green maneuvers to clear stress, alternatively you can boost for an evade then K-turn/S-loop to gain positional advantage,

D is a maneuvering beast, always finding the perfect angle for his shots. a HLC would do him well here for the same reasons as C. His ability can only be used while giving him stress, so Advanced Sensors lets you guarantee actions before your movement to improve your offense and defense. Stay on Target and Expert Handling both combo well with his 3-turn S-loops, as the opponent typically has no idea where you are going to be. Inertial Dampners is also great here, as you can use advanced sensors to trigger expert handling, then pop the dampners, letting you move sideways rather than forward (once per game)

While not played often in 100 points, A works best against large numbers of ships, as that allows him to recuperate more shields than when facing a smaller number. Making sure his attack deals the final blow to the enemy is of tantamount importance here, so a similar build to C, but with Predator over PTL is generally a good call.

For a ton of good reading on IG2K, head to the battle reports section and look for Hothie's "Road to Regionals" thread. He has (currently) 7 pages detailing his testing with various IG2K lists

I realize that I went a bit more in depth than just EPTs, so let's apply my thoughts to your list above: B and D in mind with ATs, Adv Sensors, HLC and mangler, title. I'm assuming mangler is on B, and HLC on D. If so, that is nearly my Asymmetrical Droids 2.0 list (sensor jammer on B instead of sensors), so the talents I use in that list is simply a pair of predators. Predator lets you use D's ability more freely, not caring so much about the loss of action on B when you do so, and giving D more power for his focused, predator'd HLC shot, and it combos as written above with B's gunner effect to help B land damage when evading or boosting.

Outmaneuver is also the one that comes to mind for me. Havent playtested that though... Can anyone comment?

I guess math behind favours outmaneuver if you are able to effectively position yourself, am i right?
