I just cant say WHY its that in it ?
It makes absolutely no Sense.
Everyone who invests skillspoints to get an III should be able to use it. Its already restricted
with Level of BO Consoles.
So why torture player with that limit ?
If you are going to use the same captain and ship type, you got over 36 of the same type at the end
and you dont need to train any III skills because the player ones raise too.
On the other Hand, if you mix captain and ship type its very bad for you, no level III skill for the different BOs from you Class and only one III spell from same class, BUT you must chose the admiral ship with more Consoles from your char archetyp.
To be honest thats a total failure.
So just remove the restriction to train different BO classes than yours.
