- If you have Destroyers V and Battlecruisers V update your clone to hold about 6-7 million more skill points.
- If you don't have those skill trained, that sucks, but train them as far as you can.
- If you have BC V, train all the racial cruisers to at least III, and inject Command Ships so as to get the
racial Command Ship skillsreceive ranks in the skill (Edited based on comment 5/18/13).
- Look at the links posted further down in this post to see if there are other ships that you can essentially skill into come patch day.
This dev blog has more details.
If you are a player who is fairly well along the way to a lot of T2 ships, command ships, or who remembered to train Destroyers and Battlecruisers to V, but forgot about the other requirements, you should troll through both the posts I linked to make sure you get the most out of the skill changes. I just double checked everything, and I'm glad I did. My industry character had a few skills I needed to put in my queue so as to benefit from all the changes. He will retain the ability to fly an awful lot of ships come Odyssey. Even if he can't fit any of the weapons that would make them useful...
The most important thing is to get all your racial frigate skills to IV, racial cruisers to III, and Destroyers and Battlecruisers to V.
