Yep, they should clearly add seperate skills for the long and short range capital turrets for Amarr and Gallente, since Minmatar already have to train 1 more by the looks of it.
Then it'll be balanced:
Amarr trains 2 capital weapon skills and 1 tanking skill.
Gallente trains 2 capital weapon skills and 1 tanking skill.
Caldari trains 2 capital weapon skills and 1 tanking skill.
Minmatar trains 3 capital weapon skills and 2 tanking skills.*

(Probably just shield, since armor won't be viable due to going back to split weapons.
