Full Series Possibilities for Battle of Umbara?

I love the Umbara arc. LOVE. However, I was wondering, what would have happened if Echo were still alive? What if Hardcase hadn't sacrificed himself? What if Dogma had still been in his cell when Rex couldn't bring himself to execute Krell? There are so many questions. Post a response for any of these or any other game-changing 'what ifs'!

 

What if Rex didn't realize that the clones were clones when Krell told him that they were umbarans and they killed them all?

 

Honestly I think that the fighting would have gone on and on until both sides were too tired to fight any longer

 

I vote Fives. If it wasn't for his plan to attack the Droid ship, the troops on the ground would never have received backup, and may have lost the battle.

 

You are now my favorite person.

 

Thanks.
