So, my first time playing IP (second campaign in total).

Doing the Indebted mission, only done Aftermath which means 2 threat per round.

It seems that early on there are few options when it comes to the open groups.

You get very little Threat and it feels wrong to not spawn for 2-3 rounds.

You do start with 4 threat and the options are (of course you can choose the above options on later turns, also not pointing out all combinations). The numbers refer to the turn.

0. Spawn Imperial Officer or Probe Droid directly.

2. Spawn Elite Nexu or Regular Stormtrooper.

3. Regular Royal Guard or Trandoshan Hunters.

Out of these options I think round 2 is the best. Can I really wait till round 3 to Spawn?
Sure, the Royal Guard would be awesome, but would it be too late?

My plan is to put my just bought Savage Weaponry on the starting Elite Stormtrooper group. It should do a fine job of slowing them down and since they have Gaarkhan my goal is to spread out bleed early. On Aftermath I wounded 3/4 heroes but I just couldn't get Gaarkhan down :/

I hold threat all the time, but it all matters on the situtation in the mission. You can't really plan this stuff ahead of time. You need to decide in the moment based on how many units you have left, where the heroes are, what the objective is, how many rounds left, the next mission events, etc etc.

Don't forget that you can use threat to reinforce a unit too. Especially is the unit has the Savage Weapons enhancement, it might be better to bring back previously defeated guys.

Yeah, I was thinking about that.

Especially the Elite Stormtrooper group.

3 threat for one is a good deal when you get so little threat.

Was thinking about taking in a Probe Droid on turn 0 and then have 3 threat by turn 2 to be able to reinforce the Elite Stormtrooper group.
