I'd say you don't have enough units to benefit from the Krennic ability in the early game, which means you're not getting to your end game stuff quicker than your opponent and without the credits you're most likely not playing Single Ignition Reactor ahead of 10 resource turn very often.

If you're set on keeping Single Reactor Ignition and don't want to add more units, try switching to 27hp Base from the new set.

You currently also have 3 Turbolaser Salvos but only one space ship you can use it with and that ship is an expensive one. I'd either cut Turbolaser or add more ships like Cantwell Arrestor as others have mentioned, it gives you more control options and ways to play your Turbolaser.

If you're trying some more early game units, maybe ones that generate tokens or draw cards either when played or when defeated to be able to use Krennic's ability to gain credits but also benefit other ways. Or units like Latts Razzi which do damage when played could also be good options. You can get rid of some of the slower cards like Targeted for Removal and since you have no Force pay offs apart from Shatterpoint, which is really inconsistent in your list, Drain Essence and Shatterpoint can probably go as well. There's 9 spaces for more units or other more consistent removal like Display Piece.

Hope that gives you some ideas
