There are downsides to capturing several worlds in a row like this. If all your troops get killed on the first attack you end up glassing planets. Also if you capture a planet with a resupply facility and move on during the same turn, your fleet doesn't get refueled. There is also a problem sometimes if your attack fleet has carriers in it. Sometimes your carriers will pickup your troops instead of your troop ship. Then the next planet you hit will be glassed because your troop ship will be empty and your carriers won't have the correct orders. I think you can avoid that by naming your troop ship something so that it is before the carriers alphabetically. But it's been a while since I played around with that. You can also avoid it by giving your carriers the "Capture planet" strategy in the design window. If they have troops they will drop them, and if they don't they will behave like they normally do.
