I just got promoted to Admiral, and I decided on the Advanced Escort. I know, I know, less Engineering stuff, but this problem wouldn't be fixed by switching to a Fleet Escort.

Each of these Escorts both has a Lieutenant Rank Engineering BOff slot. My Lt. BOff has Emergency to Shields I and Engineering Team II.

I need Reverse Shield Polarity, because it is suggested as a very good skill. Do I...

Scrap Engineering Team for Reverse I,

or

Train Reverse I and replace Emergency Power with Engineering Team I?

Or other suggestions, of course.
