Here are the talent builds I use for primary commanders in the open field in Rise of Kingdoms. Note that secondary commander builds are not used at all, so are not important. Note which commanders you should invest in I cover in my meta watch blog, the below list has those and some others, but only invest in that list.
My current primary commanders
Gorgo [Garrison/Defense] – Garrison build
Gorgo rocked our kvk6 garrison, especially since she can garry an offensive archer tower. 2nd is Constatine and I use Lucky Coin and Greatest Glory with this build.
Guan Yu [Skill/Infantry] – Open field
Alexander Nevsky, Huo Qubing [Skill/Cavalry] – Open field
Zhuge Liang [Skill/Archer] – Open field
Charles Martel [Defense/Infantry] – open field
Yes, I still use Martel quite often in the field. Mostly because I don’t have -every- meta commander (for example, I don’t have Sargon expertised, and until he is, he isn’t good). Double-relic’d Martel is still viable. I tend to like Martel more than Richard, but he is also a decent option for a 2nd or 3rd infantry march if you are going heavy infantry.
