When recruiting Boffs, can you assign them specifically to the away team and have them specialize in ground skills? My ensign Boffs are sufficient for my needs now so I haven't even thought about buying new ones.
Sure can, I did that in Beta, when I accidently Assigned a Tactical BO, instead of Training out the skill I wanted. I just leveled up one Tac BO with ground skills and the other with space skills. In the Away team window, at the bottom of the Assignment tab, you can set the default Away team order (top member will be chosen first, useful if you're in small teams and want a particular officer more often).
Just choose the BO for ground in the Away team and leave the other BO out of the list.
Mind you, once you have four BOs, I think the game forces you to take one instead of the generic Security team members, though I believe you can set a slot to "none' if you really don't want them to beam down. <_<
Make sure you promote your ground BO's all the way up to max level. I'm at Commander 5 so all my BO's are Lieutenant Commander. Sure it has no extra effects in space, but on the ground all my BO's have 3 powers. I am basically walking destruction on the ground, vaporize 2 and 3 enemies at a time.
