Alright I'm coming with an improved assault plan.
It will of course depend on how they use their reinforcement. I assume for what follows they would play full defensive and not try to retake planets. Of course, this have to be moderated with new infos from bananas...
If they play full defensive, we can afford to let a single ship in taken planets in response. This frees :
>51 ships in the cluster
>131 ships in Yellow
Proposed amended battleplan :
>Send 51 clustership + 12 Yellowships toward 43 +4 cluster.
Reasonning : clusterships need one turn of travel back to main fleet - but can attack other cluster quite freely if i got it correctly. This is a best used on the already deployed force. With a bit of luck they can swipe down 33/+3 cluster on T3.
>Split the planned 170 ships + 119 Yellowships on purple cluster with :
>29 on 9
>41 on 21
>46 on 26
Depending on reinforcements, either 173 on Capital [Capital reinforced] or 111 Capital/62 on42 Bluemoon

This one is a rough sketch but leverage our already deployed forces. I admit, this is a bit shitposting as long as we don't have the Esaal intel - but this should help prove this intel is valuable.
