Since we’re talking about a little reordering of episodes, I thought about the clone armour. The Phase I armour (which appears in episode 2) is used up until the Citadel/Mon Cala episodes, where it appears alongside the Phase II (which appears in episode 3), which then becomes the main armour.
Oddly, Phase II does appear in ARC Troopers (not a suprise, that was originally set a little later), but it also appears in Clone Cadets, which I thought was early in the war. I really think we need those episodes up first.
Canonically, the armour had a phased rollout, so I don’t personally have a problem with the idea that the Clone Army was launched in the Phase I armour, whilst they gradually upgraded the forces with Phase II throughout the clone wars, but I can understand if people have an issue with it.
We really should open with the Rookies arc though - it gives us some meat for Ahsoka’s light intro, makes us care for the clones, and also makes sense that the Separatists would target Kamino early.
